[Guide] How to for "1-click rooting" -Read Before Making a Thread about 1-click root

Hi guys and gals! Gee, this thread is pretty long. i wonder if it would be better if i just started another one. Oh, well.

i've got a G1 HTC, T-Mobile which has been opened. i'm presently using it in Mexico with TelCel. i'm just buying the minutes as i go. In the U.S. i use the WiFi from work and Sipdroid.

To one-touch root this thing it looks like i need to see what version of radio i have. Where can that be found? i'm presently running Cupcake, 1.6; Baseband version 62.505.20.17H_2.22.19.261 if this helps; Build DRC83.

Am running PCLinuxOS 2009, completely updated on the home computer and currently don't have any problem accessing the SD card via USB.

Do i need anything else besides the files?

Once i get rooted will the thing have some sort of desktop theme?

Will i have access to Market and be able to d/l and install the old programs again?

Thanks beforehand for any help you might be able to offer and have a great evening! :)
