I did mine a few years ago without any experience and I found the job to be more than manageable - with the seats out of the car, and the back removed from the seat, turn them over and compress the springs with a large weight (such as my ex wife). tie the compressed springs in that position (I used fishing line) and the whole seat cover comes off.
Note that the seat cover's edge has a piece of thick cardboard-like material sewed to it.
Replace the pad and put the cover back on. Note that when reinstalling the cover, the cover's edge needs to be folded over on itself so the cardboard piece fits back into the channel it was wedged into. I'd recommend looking this setup over in detail before removing anything, in fact.
Not counting the removal of the seat, the whole job is easily within the realm of two hours (or much less) to complete. Do you have the pads yet, or do you intend to buy them in the near future?
In my 114, I used successive layers of old blankets and comforters that I hand sewed to the springs. After a good two inches of thickness or so, I put the covers back on and the seat was really comfortable. I paid a heckuva lot less than I would have for the pads too...
