Are you going to be breastfeeding? To a large extent this will make a difference to how much of a 'routine' you can have. Something you really need to know is that it is not 'normal' or 'good' that a baby should sleep through so young. Some do naturally, it's true, and that's fine - but to establish breastfeeding and continue successfully it is crucial to feed on demand.
I think you would be very well served to read some of the breast/bottle feeding and sleeping threads here in order to get a realistic idea of what you have in store for you. Much better than reading baby books like GF and Baby Whisperer. I'm not anti, as such (in fact doing Baby Whisperer pick-up/put-down to 'sleep train' dd when she was 4 months was a life saver), but that wasn't about making her sleep through, more helping her to get to sleep and not to wake at the end of every 45minute sleep cycle!
Even if you are not breastfeeding, you shouldn't expect that formula will be the answer in terms of sleeping through. It does fill their tummies more, but very many ff babies are just as likely to wake every 2-3 hours for the first few months.
In terms of 'routine', I found what suited us and our dd was a loose 7-7 at night - she spends 10 minutes 'kick time' on the changing mat in the bath for a bit of naked exercise , bath, massage, breastfeed in bedroom with music and low lights, bed. The same music every night can be a good trigger for sleep. Even when her sleeping was completely up the spout (we had a couple of very bad periods which each lasted a number of weeks with growth spurts, teething, etc.), I at least found this routine gave some kind of framework.
She still has the same evening routine and almost to the day started sleeping through at six months (she's now 7months and has only woken in the night twice in the past four weeks). I consider myself very lucky to have a baby that sleeps through at such a young age, tbh.
And as for naps... She only managed those in the pushchair until she was well over 4 months - now she does pretty well, but I thought it would never happen.
I would say you and your baby will both be much happier if your mantra for the first few weeks is 'go with the flow'.
