I looked up the 2030 charger, and yes, that will charge three cell packs just fine. You will probably want to get a balancer at some point, but you can live without it until you can find one. I like the Astroflight Blinky. It will work with your charger, costs only $25 and can balance just about any pack you're likely to encounter--there is an adapter to fit most packs that the built in port can't handle, and it only costs $4.50 additional. As far as the nimh battery/prop combo goes, you will probably see a performance increase from the 9x6 and 10x5, but I don't know offhand if you will find it suitable or not. As long as you've got the plane under control, the worst thing than can happen is an underpowered glide to a landing, right? Can't hurt to try the new props before investing in Li Po. I did successfully fly mine on an AXI and 8 cell nimhs for some time before moving to lipo.
