Keep in mind I'm taking 16 other hours, have a part time job am on two sports teams, and am in multiple organizations on campous so I don't have oodles and oodles of time to devote to reading resources on the subject that I have to look up raondomly on the internet.
Are you trying to make us feel sorry for you? It is not working. Ever think about priorities? The time spent playing(sports) could be spent on learning.

External oscillating circuit is a must. The data sheet gives several examples. I like the crystals with built in caps, one part top do the job and the 20Mhz is cheap.

I just thought you might need a breif pause between sending the first hexadecimal command to the LCD and the second. Can I just send one right after the other with no break?
Normally I would say no, but with out knowing exactly which module you are using I can not look up the DATA sheet to give you a good answer.

Fix the things Shimask pointed out, do some more reading and get back to us if you still need help.
