Hello Nursee and congratulations on the impending arrival of your baby.
I am sorry to hear you have SPD, that is tough. Someone here mentioned getting good equipment to save your back. I think it applies in all cases. The evening we got back from the hospital after DS1's birth, my husband got a cot top changer (thank god for late opening hours) as both our backs were killing us. We also have a sling (Kari-Me) and a little towelling deckchair for the bath. A sturdy breastfeeding cushion is definitely a god's send.
I was all geared up for the birth, but of course it did not match the birth plan. Try not to be disappointed.
After that, I struggled to get breastfeeding established: I was plagued by sore nipples, poor milk supply and terrible thrush.
So I second advice above: be strict about latch, you need to teach your LO how to do it, and the sooner the better. This will help your milk supply, but don't hesitate to get your midwife to prescribe domperidone if necessary. Using a breastpump is not ideal IMO to stimulate milk production.
Get some privacy until you have the hang of it. After that, you won't give a damn. 
If you feel any pain at all in your breast tissue, it could be thrush or a blocked duct so get it checked IMMEDIATELY. Don't worry about sounding silly, better safe than sorry. And if you find your GP is clueless, get a second opinion, do your homework (breastfeeding network, Dr Jack Newman, etc.).
It is true BF can be difficult in the first few weeks but it is so worthwhile in the long run. Think of it as breaking in a pair of really good walking boots.
BF is convenient: always ready, no washing/sterilising, cheap, etc., but it is also very good for your confidence, it is such a reliable tool to meet needs, soothe and relieve pain. I have always viewed it as a continuation of nurturing my baby during pregnancy and it helped me get over the end of the pregnancy.
I guess it works for the baby too. It is comforting to hear the mother's heart beat, feel her warmth (and vice versa) and smell her scent.
Drink fennel tea to help with baby's digestion.
Hair clip on bra strap to remember which boob you used last.
Once you are back at home, try and lie down as much as possible for the first 6 weeks. I know it's easier said than done. Give your body time to recover. Arrange a long visit from your mum after the end of paternity leave.
Sleep: my DS2 just wouldn't put up with the moses basket so he slept with me for the first 3 months. I kept my babies close at night for 6 months+ so I could just pick them up, bf them and pop them back. Bf whilst lying down is great, and don't hesitate to go back to sleep, you will not squash your baby. Nap if/when you can: how else can we survive?
Who cares about a little stain here or there? And I mean baby clothes as much as housework. Those who care can clean them for you. This is said with hindsight. After the 1st birth I remember manically scrubbing the bathroom tiles and doing the book keeping. Much easier to relax second time around!
A good piece of advice I got from the NCT teacher: babies are tougher than we think; if they can survive isolated for a week after an earthquake in Mexico, they can cope whilst you have a pee! However I think they do need a fairly quick response to reassure them.
I made the mistake to think I was still the boss. Your life will now centre around a little being who needs your help to meet his/her needs. Lots of cuddles indeed as this can be frightening.
It may seem like a huge responsibility and you may feel out of your depth. Don't think you're crap. If you do, especially if you think of leaving or harming yourself, get yourself seen by your GP IMMEDIATELY, as you may be suffering from post-natal depression.
Getting used to not being the centre of your own life, as said before, can be difficult. So try and find some time to connect with yourself, to limit the resentment. I find a craft activity works better than TV.
Read What Mothers Do etc as recommended before.
Other practical tips:
Get hold of little saline solution bottles to squirt into baby's nose to loosen boggies, suck them out with a nasal aspirator of some description and use olbas oil.
I still put my baby on a bath mat on the bathroom floor whilst I have a shower.
We also indulged in having a bath with our DSs. Definitely a good job for Dad to help bonding.
DH also loved carrying DS1 and DS2 in the sling (sometimes on his bare chest to do skin-to-skin, bless him) and taking them to the park. He worked out DS2 liked leaves very early on, much better than I did. Everyone's got a role to play. (My brother-in-law played ping-pong whilst carrying my nephew in the sling.

A pedicure will always make you feel like a million dollars.
Outings: I vividly remember the 1st one in the car with DS1 in the back, it seemed so difficult! Have a go, it will get easier.
Get a tumble-dryer for mother's day.
Tinned soup.
Online supermarket order: oh yes.
Get used to eating cold. Don't bother with tea, just stock up on nice smoothies and fruit juices.
Cranial osteopathy for both of you.
Baby massage, mum and baby yoga.
Lots of photos. Keep a diary.
titferbrains is right: don't bother to look at your watch. Take it off anyway as you will need to wash your hands a lot. Time works differently: you need to take it slow and at the same time you will find you seem to have no time at all.
Enjoy!
