Reset PPC-6700 back to factory settings?

[Stingray]

Hi Guys,
I just bought a PPC-6700 for Sprint. Since I just got it... Im really excited about it and in that excitement, I will probably install 1000 programs on it just to try them out..... at some point in time i will want to uninstall all the unnecessary programs and just keep the ones I really want...
In this regard, I have 2 questions......
1. Is there a way in PPC-6700, where I can reset the entire Phone/OS to the original factory state? where i wouldn't have to worry about uninstalling anything or cleaning the registry?
2. Will this reset clean up the registry (Including the manual tweaks that I am planing on doing in the first go) and make it just like it was out of the phone box?

I really don't mind re-installing the programs I need from scratch (Including contacts)... Quite honestly I would much rather do that, than having some extra program taking up the processor.

Thanks guys...
