Can't help with co-sleeping queries at all, we ended up being the opposite end of the scale! DD1 slept in a Moses basket on a stand next to my side of the bed for the first few months, at which point she was evicted into the cot in the nursery next door. Otherwise we used to disturb one another; We all slept much better with her in a different room.
It worked well for us as DD1 was relatively easy to settle, loved the space to herself when she slept in the cot (she hated being constrained/swaddled/etc - still does!) and slipped into a convenient routine quickly. She also was, and still is, fiercely independent. For a different natured child, then co-sleeping might be ideal. I've heard good things about it.
Posting my experience mostly to reassure that different things work for different people and there is no ideal solution for everyone. :) A lot of it may depend on the personality and preferences of your lovely LOs!
Waiting to see what DD2 is like with some trepidation... We got off so lightly last time that I fear we're due a nightmare with a non-sleeper, non-eater, limpet child!
You have my sympathy, MrsFooCough! I had that joy last time around. Had a procedure done to reduce them between pregnancies and, touch wood, thus far they've not made a reappearance. Helps that I'm craving fruit rather than stodge this time, I expect. 
Not sure there's much they can do during pregnancy, but if they're still a problem afterwards then get thee to a GP and insist something is done. The procedure itself isn't exactly pleasant, but after I'd recovered then having them resolved was wonderful!
