If you do a search there are a few threads detailing the registering process - I know I used them. My rough rememberings say:
1) order the import pack from gov asap
2) insure on the vin on arrival
3) mot against the vin
4) fill out forms as best you can, don't need a certificate of conformity if it's overs 10 years old
5) get the v5 through with a week or two and get down your local number plate makers!
6) forget to tell your insurance company the new number plate and get accused of driving without insurance.
It's a surprisingly easy process to be honest.
