Do it yourself Oil Change questions

So I've decided to do my own oil change as the dealer is too far and will probably charge me alot anyway....even though a friend did suggest I use them during the warranty period.

What type (brand & model) of torque wrench can I get online so I can tighten back the bolt at the recommended torque? I will also probably use it on other bolts that need torquing.

Where can I get an original new sealing washer to put on the drain bolt?

Thanks!
