I'v been running a 4.8v pack's on my profiles and would like to go to 6v's. My question is can I still use my normal wall charger that I use for my 4.8v packs or do I need something better?
Yes, and yes.
I suggest checking out Red's R/C Battery clinic for more information.

Edit: when I started using 5 cell receiver packs, I finally broke down and spent the money on an Accucycle Elite. One of the best purchases I've made in a long time. Works great!
