568B is the most common standard. If you go to the store and pick up any CAT5 pre-crimped cable it will be 568B.
Also, if you make a cable with A on one side and B on the other you'll have a crossover cable.

When wiring inside wall jacks, follow the punch down color coding. 568A & B wiring is used for cables only.

If it's color coded, wouldn't it be coded to the A or B spec as in this diagram?

The normal standard for use in cabling buildings is 568A, because of backwards compatibility to the older AT&T 258A, which may still be in use in older buildings. 568A for this reason is still specified in Government contracts. This might make the difference a little bit clearer:

Ill wait for my patch panel to arrive before wiring any up. So either way i go, A or B, it will commicate with my modem, correct?

Are you connecting from a switch to the panel or direct from the router to the panel?
