Custom Rom Questions

[Guest spidermagicat]

Hi, you've earned another new member through your brilliant work with the HTC desire, I've successfully rooted and now unrooted my htc desire completely without any problems or hiccups at all and I was pleasantly surprised. I have had to unroot my htc desire because the microusb socket broke and I've sent it back for a replacement, arriving tomorrow.

My main question is this, if I build a custom rom will I have to include everything I will want or can I install/uninstall some things later?

HTC footprints I don't use but may in the future for example. Google contacts I would like to try and may want to get rid of it

The other small thing would be about the radio update working on orange which I'm also curious about.

I basically want to nail this in one try if possible and not go through a month of tinkering to get things done :-D

Thanks for any help guys, and as I say, great work :-D
