There are a MILLION aspects to VHF/UHF DXing. Meteor Scatter, Digital, Moonbounce. . the whole ball o' wax.
Depending on what you are interested in, there are websites available to learn from.
Here are some sites, covering a variety:http://www.go.to/beaconet

My club (The Rochester VHF Group) has a website which has tons of links as well.http://vhfgroup.rochesterny.org
Start there. Depending on where you live, might try to find a specialty group that caters to VHF and above operations. They'd be more than willing to help you out.
