My Sprint TP2 runs slow. Help

[JohnMcD348]

I have the Sprint HTC TP2 and updated the OS with the factory OS after it came out. I haven't run any cooked ROMS since I need reliability since I use this for work as well as fun. When I go online to things like YouTube and such, the system seems to run slow. It takes along time to buffer and then rebuffers during playback. Also it seems to hang a bit when switching applications.

I've installed the HTCAddicts cleanRAM and use it pretty regularly. I've installed quite a few programs but most of them, I thought, were on the storage card. But, when I checked it there seems to only be 43mb of memory on the phone remaining. I can't seem to figure out how to look into the phone itself to see what's actually installed on the phone memory compared to the storage card. Would moving programs to the storage card and freeing up memory help with my problem or do I need to look elsewhere for the solution?

Thanks
