For checking frame alignments I used the Park *** tool. It stands for frame alignment gauge.
Its simple and easy.
Then you'd prob want to check if the headtube and seat tube is parallel.
I use a carpenter's tool, I think its called an angle locator.
Then you should check your dropouts.
Park makes a cool tool that lets you check if the dropouts are parallel to each other.
And if not, you just bend it back till its aligned
most importantly, if you bought the frame used, run you fingers under the tubes and near the headtube to check for any ripples or dents.

And as for wheel builders, ask cavernmech to do it
+ when I was wheelbuilding shopping, he had the best price too.
he's a super duper guy!

On another note, I FINALLY finished all my exams.
& I started my new job today. and @ my new job I learned how to lace wheels.
