I got an Arduino Uno micro controller kit for my birthday. It didn't come with a power supply. It's rated to take a power supply between 5 and 12 volts.
I have the following power supplies that could work, need to figure out which one would be best:

5.1v @2.4 A
12V @500 ma
5V@1500 ma
5V @ 1A

I'm thinking that 5.1V @2.4A would be best because as I add daughter boards and stuff to run off the Arduino power, more amps is better.  Is my thinking correct? I'm new to the hardware game, much more comfortable in the software side of the equation.

Thanks for any help.

That's what I would pick.  No real downside to having a supply with a little extra capacity, and probably less heat stress on the on-board regulator if you are at the lower end of the acceptable voltage scale.
