21'' wheel Spoke spec torque

[TheGammaGhost]

Hey chinariders! have a quick question, I tightened a few of my spokes on accident with out even thinking about the tire alignment, and it resulted in a slight wobble in my front wheel. I jacked my bike up and, and I've got it basically back to normal right now, but i want to know that the spokes aren't to tight or to loose before i put serious miles on.

Anyone know the spec torque pundage they should be at? and, if i went through and set them all to spec, should the tire be about perfectly aligned on the hub?

also, I have no idea about torque wrenches, do they only come in one poundage? and how much would one for this job cost, roughly?

Thanks!
