To Mickey's list I would add a few things and make some adjustments: I would get two different size T pins 1" and 1 1/2". I would add some instant set to the CA for when you need a quick tack. If you are like some of us and can't handle the fumes from the regular CA try the Foam safe CA, less fumes and no stuffy nose afterwards.
Hobbico makes a small set of metal Builder's Templates in different shapes made out of aluminum I find the set really useful. I would also add the Hobbico Build's triangle set. They are clear plastic and designed to fit together o free standing. One triangle has slots to determine the most common wood thicknesses. Both can be had for around $7.00 a set. Xacto has a nice 3" triangle that doubles as a ruler as well. I own them all. My miter box is a little aluminum job from it came with a razor saw and was less than $10.
YOU MUST HAVE if you don't already have one of each a good airplane balancer and a prop balancer. A properly balanced airplane will fly a lot easier and be more stable then an unbalanced plane. A balanced propeller will but less strain on the motor and give better performance. When I was young and stupid I learned this the hard way. Now I'm old and still stupid but I know better.

Shop at your local hobby shop first, if they don't have it they can get it and they are worth their weight in gold when you have a problem. You can learn a lot just hanging out with the other builders regardless of your experience. It's a lot like RCU only smaller.

Lastly I would recommend a steel 12" ruler over a 12" wood rule. I have metal rulers start at 6" and going up to 6 feet. The 6 foot ruler is real handy if you are going to use Monokote or Ultracoat for cutting long strips for the wing sides. I prefer to buy my Ultracoat in the 10 meter roll and my Monokote in the 25 foot roll on the base color. It doesn't save any money but does appear to make for an easier layout with less waste, just my opinion. I will sut up now!
