Clinchers use a tube and a "bead" to hold the tire onto the rim, they are the most commonly seen wheels. Tubulars aka sew-ups or glue-ons dont use a tube and you literally glue them onto the rim. Tubulars use to be the easily superior choice,but with time, clinchers have improved dramatically, so, unless you want the very best performance, use clinchers as they are cheaper, easier to obtain, you can switch tubes, and they are almost as good performing...even some of the top pros are gradually switching to clinchers supposedly...

here's a good source for lots of stuff:

http://www.sheldonbrown.com/glossary.html

clincher=This is the normal type of tire, with a separate inner tube. The tire consists of two hoops called "beads", made of steel or Kevlar cable, which are held together by cloth, usually nylon. The whole assembly is dipped in rubber, with thicker rubber applied in the tread area.
A clincher tire has a separate inner tube, which is basically a rubber balloon. This fits inside the tire, and the tire is mounted on the rim by lifting the beads over the edge of the rim. The middle of the rim makes a sort of valley, and while the tire is being installed, most of the bead can fit into this valley. This gives enought slack to allow the bead to be pushed or pulled over the edge of the rim, even though outside diameter of the rim is larger than the inside diameter of the bead.

Strictly speaking, the term "clincher" is slightly incorrect, as it applied to an obsolete style of tire which had ribs in the edges of the tire which fitted into grooves on the rim, where the tire was folded under the tube. The air pressure in the tube pressed the rib into the groove, and "clinched" the tire in place. People who are fussy about this prefer the term "wire-on."

tubular=A type of tire mainly used for racing. A tubular tire has no beads; instead, the two edges of the carcass are sewn together (hence the term "sew-up") with the inner tube inside. Tubulars fit only on special rims, where they are held on by cement.

For a beginner just do the clincher thing.

Tubulars are supposedly a smoother ride and you can run higher pressure...ie less rolling resistance. It come with a big pain in the butt price. The tires are more expensive and are hard to put on rims as well as fixing a flat. Many of the best carbon rims use tubular because of the nature of the material.

Clinchers are becoming almost as good as tubulars and many pro level riders are using them now. A lot of advantages for the beginner with out a personal mechanic, easy to fix flats, easy to change tire.

Seriously, despite the opinions of certain sourpusses (such as kerry irons, sheldon brown, and other such opined riders), tubulars are not just for racing. Still, I wouldn't suggest having tubulars on your one-and-only bike. A second wheelset, maybe, or even a seperate bike riding on tubulars. Even I don't ride them every day!
