Might as well throw in the popular ones:
K-ON season one - Season 2 will be airing next month.
Lucky Star (Slow to start, but worth the wait)
Full Metal Alchemist - Brotherhood (Much better than the first one!)
Inuyasha - The Final Chapter (YES they are finally ending it!)
Ouran High School Host Club (High School never ends
)
Melancholy of Haruhi Suzumiya (You can decide what order to play them, and if you want to include the endless eight)
Shounen Onmiyoji (It has an Inuyasha feel to it)
KenIchi: The Mightiest Disciple (One of the best fighting shows ever! Has a Ranma like feel)
Combat Butler Hayate (One of the best parody animes ever)
Shugo Chara (For the young at heart, or just plain young)
Azumanga Diaoh (Try not to laugh yourself to death, remember to breathe)
Zetai Karen Children (Has guest appearances of CB Hayate)
Kobato (You gotta have some CLAMP!)
Nodame Cantabile (Learn your orchestral pieces and composer history while enjoying a good comedy drama)
Saiunkoku Monogatari (Better than Fushigi Yuugi in my opinion)
Cross Game (One of the only sports anime I ever liked, Have tissues handy for the first episode)
These should all be OK for a school club. Let me know if you need more.
I can provide you with all these files, plus the other anime you mentioned, if you bring over an external drive, or a pack of DVD+R's
