Root Noobie Question: How to install a patch

[NiteRider]

Is it as simple as placing the zip file in SD root, restarting the phone in recovery mode, and install the zip?

Are backups needed for just patches?

I am aware of one patch so far for froyo and it's http://adrynalyne.stfuthxbye.net/n_patches/stagefright2.zip

Is there a different patch I should be looking at?

Any help is appreciated. Explain it in a cool way and you will earn style points.

Your first 2 lines are correct. It's always a good idea to do a nandroid just in case.
