New to flashing htc

[xanronin]

I would like to know more about flashing phones specifically a step by step guide on how to flash a phone. I have a mogul (6800) and I would like to see about flashing my phone but I don't know exactly how or how I would reset all my carrier data. I have seen some carrier cabs around but I'm afraid to install anything like that because I do not want to brick my phone and then be screwed. If anyone can just give me some pointers or at least point my in the right direction I would be very thankful.

Ok so I downloaded the RyanMogul Carrier ROM 2.2 Light for MetroPCS. But I need to specific bootloader and radio. I need to download the bootloader and radio install those somehow and then install the carrier ROM, correct? I'm assuming that I will be using activesync the whole time. Do i need to do a hard reset in order to install any of these files? Thanks for any help you can provide.
