Never used temp root program z4root, I'm permanently rooted, just easier for me that way, and I use wireless tether or you can use hotspot or whatever you want to share your phones internet with a computer.

Your going to have to make sure your phones not rooted, update to gingerbread and then use revolutionary to root it, don't think you can update with root from what I remember, plus you would lose it anyways when you updated.

Personally if it was me I would just root the phone and put a custom rom on the phone and be done with it and then you won't have the bloatware you don't want and can install programs that you want that are not already included in the rom.
