Looks like a nice tri..

3s 25c  2200mah looks about right.. http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=31978

Yeah KK board and Turnigy Plush ESC';s

Props are Rctimer 10x4.5.. they look a bit big for that setup.. 9x4.7 might be ok as well www.rctimer.com

Charger http://www.hobbyking.com/hobbyking/store/__25406__Turnigy_Accucel_6_50W_6A_Balancer_Charger_w_accessories_UK_Warehouse_.html   This will need a 12v supply..

The C rating tells you how many amps the pack can supply, the higher the rating the more amps you can get out of it.
Generally speaking a 25C battery is good enough for most set-ups but if you';re into aerobatics or anything where you are going to want a very responsive setup then a higher rating is good; I use mainly 25C for my quad but have a few 35-45C I use when it';s windy just to have a bit of headroom.
Oh and the Zippy compacts Jumpy has pointed you at are the mutts, I';ve only recently started using them - the advantage of them is that they are smaller and lighter than the normal equivalents.
