I saw the seats on eBay yesterday - they will bolt right up to yours. I don't remember that they had any power options, so it should be a simple swap. Beware of the connections for the airbags. Unplug your battery before you disconnect anything or you will set off the airbag light and have to have them reset.
There is a good guide for swapping seats I've used. I'll try to find it for you.
edit: Here's the link. This shows swapping in GT3 seats, but the electrical connections are the same. The bottom of page 1, page 2 and page 3 are what you need to focus on. Take your time, follow the guide - not that hard to do.

Edit, edit - your plugs will be the same - no worries.
