What to do First ? - (Update) Failed to activate

Just got my new Touch Pro2 in the mail today, i will be retiering my Titan and activating the TP2 on the Verizon network.

Question: is there anything i should do first before activation?

I plan on installing one of the custom rom and have already downloaded HardSPL to unlock the phone.
Using the phone with Verizon is there a need to upgrade the Radio at this point?

Just want to make sure before fire this thing up.
