For the first few weeks it's really just:
Baby wakes up, cuddle baby, feed. The feeding bit might take anywhere between 10 mins and 45 mins (or longer) - some babies are marathon feeders, though both mine were sprinters in the feeding department and wolfed it down in 10 mins flat!) In the first few weeks you are getting BFing established. You can't offer the boob too often! Each feed helps to stimulate your supply and get it all going. If baby is crying and you can't do anything with him/her, feed. As often as you like! If you keep feeding and baby is still crying and you can't get them to settle, then it may be wind (see below) or baby may be overtired and need to get to sleep but can't (in which case try helping him/her to sleep by rocking or driving somewhere in the car). Or they may be upset as they have a dirty nappy (though I have to say mine were ragamuffins who wouldn't have minded being dirty all day long).
After a feed cuddle upright and rub back to burp and wind etc.
Baby might be awake for a bit after that. Change nappy if poo-ey. Baby will probably start feeling sleepy again after a relatively short time (certainly within 2 hours of waking up), so you feed again. After a feed s/he will be sleepy.
S/he might be a baby who is quite happy to be laid down in his/her basket to sleep, if so you would put him/her down. If you get one that doesn't like being put down (and a lot don't when they are tiny), you would cuddle and rock till asleep then put down gently, or perhaps s/he might sleep in the pram with you rocking it back and forward till baby's nodded off. Or if you get one that wakes up as soon as you try to put her down, like my DD, you could pop her in a sling and carry her on your chest while she sleeps and you do whatever you want to do.
While baby is asleep get yourself fed and watered and showered, arrange things on the sofa (water, biscuits, iPad, TV remote)
Then the whole thing repeats itself each time baby wakes. Baby is likely to wake more and be harder to settle in the evenings say from 5 to 10pm. Given the evenings are getting lighter and warmer, you might find yourself doing an evening walk to settle baby during this fussy time, with baby in sling or pram.
By about 10 weeks or so, you might start doing a bedtime routine - bath, feed, and into bed - and after that all feeds in the night upstairs and in the dark/quiet. When they are really new there is not much point doing this as they are quite fussy from 5pm to 10 and the easiest thing is just to keep them near you. But you'll probably notice there comes a point where instead of settling better, they start to need less stimulation and peace and quiet - that might be the time to start bath and bedtime. In the first month or two we only bathed ours perhaps twice a week. I don't think my second, DS, had any all over wash at all after birth till he was about a week old. He wasn't at all gungey - in fact he was fragrant, ha ha! Once they were getting on for 3 months though they had a bath every night as part of bedtime.
After a week or two you will probably want to start going out for a change of scene. You'll get a sense of the best time to do this - usually you would feed and change the baby and then set off - they will sleep in pram or car.
As the baby gets older, the sleeping time gets less, and the awake time between feeds greater. Then they might enjoy things like baby gyms etc. But in the first 8 - 10 weeks they really just want to be close to you, feed and sleep and look about them a bit.
Babies have growth spurts where they feed more and for longer, and do not sleep for as long. They can be hard work, but don't worry that "everything has gone wrong" - it hasn't. Its a growth spurt, they are feeding more to up the supply of breast milk. Just go with it and be led by what baby wants. Things will settle down again in due course (hopefully sooner rather than later ....)
The best advice anyone ever gave me was to treat the first three months as a "fourth trimester". They are tiny, curled up still and they just want snuggles. From three months onwards they are more outward looking, and much more alert. By six months they are sitting up and covering themselves with carrot puree! By 9 months they are crawling or nearly crawling, and by 12 months walking or getting close to it and rifling through your cupboards. And by 18 months your little one is a child, not a baby - a full little personality with likes and dislikes and preferences, who can make you laugh (and cry!) and has a strong will! By 2 they are starting to talk to you. Then the fun really starts ... And before you know it they are 4 and off to school, and their horizons expand outwards from the nucleus of the family and into the big wide world. Sob (my eldest starts in September!) 
Good luck OP, you're about to embark on the biggest and best thing you'll ever do. It's a miracle, really it is. Note to self, you do NOT want another child. You can only just about manage the two you have got !!
