Night nappies advice

Kay
Hi, I'm due my first baby in September and am very keen to use cloth nappies 24 hours a day. I hate the thought of throwing 1000+ nappies in the landfill a year. So far I've bought 15 bambino Mio all in one nappies (I went for all in one because I really don't know what I'm doing and thought they'd be easier for starting out). I know I probably still need a few more so if you have any suggestions on how many and what make please feel free to comment. 
My real reason for posting, however, is I really need some advice for nighttime nappies. I don't know anyone who uses cloth so I have nobody to ask advice from. Are two part nappies better at night? I know bamboo is much more absorbant, but takes longer to dry. I am okay with that though as I'll get about 5 night nappies. What brands should I buy for night? What exactly do I need? How many boosters should I get etc? I'm living in the UK so won't have access to all kinds and brands, just the bigger brands but if people generally think a brand is the best and I can't get it here I can have my sister in the US order it for me. 
Thanks for reading, and thanks in advance for your help.
