Terry nappies can be fab as they are adjustable to the size of your baby and easy to wash and get dry, although I also used shaped. Having had my 5th child in June, really cloth nappies are not as much of a faff as you might think (and I have probably saved a massive amount of money over the years).
With regards to the Babybjorn-style carriers - they are not necessarily ideal when it comes to babywearing and there are likely more comfortable slings available (somewhere like http://www.thebabywearer.com/index.php
would have good advice). If you're wanting to use a sling (and I have done so when I've been capable for many years now - my eldest son is 18 and, like I said, my youngest is a few months) then you really need to be looking at a sling that really distributes the weight well across your back - especially bearing in mind the extra strain that this can potentially put on your body.
Much as I love using wraps and mei-teis for carrying, it can sometimes be a struggle and I have to use a pushchair more than I like
I really wish I could carry my baby more, but the c**p fact of the matter is that I can't for any distance (although I do try to go for short walks with her in a sling as I home-ed and try to give my younger children an airing in the woods/fields by here when possible).
I have always co-slept - but do have a cot pushed up against the bed with one side off to create a bit more space when needed.
A large firm pillow (or special breastfeeding pillow) can really help with breastfeeding - especially in the early days when you're getting used to it (because it can and does take practice).
I have to admit that although A is almost 5 months, I have never bathed her, OH does this job (because I've not been able to - although I haven't always had this particular problem and did manage with the others).
Pay attention to how you lift baby - be gentle on yourself. x
