If you are serious about this, you will need to invest in some basic tools. If you have a decent hobby store in your area, you can find precision pliers, screwdrivers, etc. similar to what's on this site... http://www.micromark.com/?gclid=CJ7U3a30yacCFcfe4AodZSvLEg
For screwdrivers I would suggest these...http://www.amazon.com/Wiha-26199-Slotted-Phillips-Screwdriver/dp/B000NZ5QG0/ref=sr_1_1?ie=UTF8&qid=1299963475&sr=8-1
They are the some of the finest made and they will last a lifetime.
You should also have a small pick set in addition to good screwdrivers and a variety of pliers. A 1/4" drive socket set (metric) with shallow and deep sockets is helpful also. You could have walked that clip out with a tiny flat bladed screwdriver or a pick. ALWAYS keep a finger over clips as they will shoot across the room never to be seen again.
You're on your way, just keep your head and learn to walk away for a few minutes when things get **itty.
One more thing I do is note the orientation of every single piece. Often there are subtle differences between, for example, the two sides of a gear or washer. Schematics usually don't show the detail of smaller parts. Some guys take pictures, I sketch them on paper. Details are everything when it comes to working on reels.
