Not knowing the specifics of what you have planned, I have to say you did a great job shopping. The only thing I would change is to replace the silver bearing solder with this:
Lead-Free Solder (0.25 Oz.) - RadioShack.com
The silver solder has a place, just not so much with the tiny parts we are working with. It requires much higher heat than our little plastic parts can take and doesn't provide any advantages for this application. Rosin core solder contains a core of flux which is helpful and melts nicely at temperatures that a small wattage iron can achieve. That is the exact soldering kit, push buttons, and shrink wrap tubing that I bought to start out with.
I am excited to see what becomes of this. Please keep us posted.
