PPCGeeks - RSS Hub and Theme questions......

I should start off by saying that I am running the Stock ROM that came with my US Cellular Touch Pro (CDMA).

I have 2 questions.
1. Is it possible through registry editing to make RSS Hub use a diff search engine for finding new RSS Feeds? The Live Search option isn't yeilding any results and when I choose syndic8 the results dont pertain to what I was looking for. When I was looking through the registries I found something in the RSS Hub section that said SearchEngine but I wouldn't know what to do with it.

2. Since I am pretty new to this and still using stock rom, I was wondering to change TF3D themes do I have to do anything special ex: unlock the phone, flash new rom? I would like to really trick it out but I work alot of OT and time at home is best spent with family, so that really restricts how much i can do. Mainly the only things I can do are what is possible from the phone itself during my loads of downtime @ work. I guess im just curious if I can download a pre-existing theme from my phone and install it with a stock rom without the use of a PC.

Thanks for any help you can give
