That is all good to here, since this seems to be a fairly common DIY type thing, could you maybe get somebody to take pics of the important steps while you're doing it next week? If you can't that's cool, but if you can that would be a wonderful addition to the DIY threads and the website as a whole, sorry I haven't done it before or I would have popped in and threw a few lines of wisdom your way.
WISDOM
Slow is Smooth, Smooth is Fast.
Take your time man, it makes all the difference in the world. If you get frustrated keep something nearby that you can hit, or throw or something. My buddy Mikey keeps a punching bag in his garage for occasions like that. He moved it into his garage because he never really used it in his house, he sort of started using it as a stress reliever by accident.
