RE sleeping, last time we had a moses basket in our room and then the pram which we chose had a proper mattress and was safe for overnight sleeping so we used that during the day downstairs AND when we went to visit people (which we did a lot) used it at night at their houses - it was very handy. DS was a fairly small baby and lasted in the moses/pram till 5 months. Luckily for us our cotbed fit in our room and we kept him in with us till he was a year.
Whoever asked if its ok to out them straight in a cot in your room - absolutely! No harm at all and they will be used to the cot from the very beginning (and unlike us you probably won't install it in the nursery and then have to move it to the bedroom). They will look very very tiny in it to begin with, possibly a bit bare but it doesn't matter, just don't be tempted to fill the space with fluffy things which could be dangerous (both for suffocation and also important to keep air flowing around the cot to avoid overheating). The only thing to note, and it does depend entirely on the layout of your room is that maybe the moses basket would fit closer to your bed, which would save you a lot of movement in the early weeks but it depends on your room.
We have a slight change around this time, our new house has smaller rooms and it won't be possible/easy to fit the cot in our room but BIL/SIL have a bedside cosleeper which we will borrow (Will get new mattress), its bigger than a moses basket so fingers crossed will last till baby is in his/her own room, otherwise serious thinking will be needed! We will then use the moses basket in the lounge and still have the pram for overnights away from home.
Phew! That was long!! PS since we are talking sleeping I thought I'd share: I adore bags sleeping bags and DS has only just stopped using them at 2.10 but you should note that they can't be used till baby is (I think) 8lb13oz or similar and thus you might need to have an alternative for the early weeks/months - DS was 7lb3oz and didn't make it in to the sleeping bag for 2 months iirc.
