as long as you have the proper chain slack, you are fine. As far as the geometry of the bike being messed up, don't worry about it. The difference wont even be noticeable. just sit back, look proudly at your work, and have a beer.
also, as the new chain is used, you will periodically have to move the adjusters. if you have any question about this, send me a PM and i will gladly help.
