Remember that having a baby is hard work, whether they arrive naturally or by section, so do not feel guilty for feeling tired / not doing what you usually do around the house. Accept that your body has been through a lot in the last nine months, and ignore the pots / ironing etc.
If you have guests around, don't run around after them, if they want a drink, they know where the glasses/cup/kettle/tap is. And get them to wash their glasses / cups afterwards 
Internet shop for food.
Use your midwife / health visitor after the birth. Dont worry or feel silly for asking questions. We've just had our second baby and still freaked out about his belly button having forgotten everything about having our DD five years ago! The HV / miwife will have see and heard it all, use them as a resource, but don't feel you have to take their word as gosple if they're not very nice (some threads on here) and request to see another HV if you dont like yours.
Don't feel pressured to get back to the swing of things too quickly, especially in the bedroom. You'll be knackered, hot and bothered, knackered, stressing about your post baby body, knackered... your partner will undersand.
If you breast feed, accept that its hard work to start with but it does get better, and when you get in the swing of things, you will wonder why you found it difficult to begin with. Its a skill you and your baby have to learn together in terms of positions and what suits you. (I remember crying with DD because I didn't know how to get her latched on, within a week or so we were a dab hand at it!).
If you have sky or any TV where you can tape stuff on the telly in your bedroom, stock up on stuff you can watch in case your LO demands an hour feed in the night; I've been watching ER reruns, and find the break in sleep goes quite fast looking at George Cloony!
Accept that your emotions will be all over the place. I sobbed for an hour after DD was born because I wrote something wrong in her baby record book. Accept that the hormones will settle.
If you want to save yourself some washing, just stick your baby in a vest in the day time if you are not going out, especially in the hot weather. They don't always have to be dressed up "properly" (I learnt my lesson with DD!!)
Take a deep breath with the HV does the heal prick test. Both times I've wanted to hit the HV when they've been doing them to my babies. The tests are really important and it doesn't really hurt the babies (and they forget quickly!) but you will be muttering names under your breath at the HV! If you can remember, make sure your LO has warm feet before hand.
Cuddle your baby lots, and accept you will fall head over heals in love with them at some point. This may be immediate, this may be after the initial shock of the baby actually being there has worn off, or it may be later, but you will (as others have said) find yourself staring at your LO with utter contentment and wondering where the last hour has gone.
If you can, get your DH to knock up a sandwich for you before he goes to work, and leave it in the fridge for you. That way, at least you only have to fetch it to ensure you at least eat something.
When you feed in the day if breast feeding, settle somewhere comfortable, and have the TV remote, the phone, a drink, a biscuit, and whatever you may think you could need in the next half hour.
Learn to smile sweetly at people when they give you advice, and if you are not sure of something, but sure your mother/ grandmother/ inlaws are wrong, ask on mumsnet.
Dont worry too much about routines in the early days. Ignore anybody who says you're making a rod for your own back, just go with the flow and you'll see a routine has developed all on its own :)
Hope this helps :)
