Default New to LG's - question about returning to stock

Bought an EE locked D802, I'd like to install the Vanilla 4.4 rom so I get any future updates direct from LG OTA.

I've done some reading and I can see I'll need to leave the stock recovery to get future LG updates.

Also want it SIM unlocked.

Are the steps;

1) SIM unlock from unlockcode247.com
2) Root
3) Install stock 4.4 rom (which is the UK vanilla rom?)

Anything to watch out for with the EE UK D802 variant?


Done?

Thanks.
