OK, I'm a bit confused, but I think what you've got now is:

internet ---- cable modem ---- Linksys ---- m0n0 ---- PC

Assuming that's correct, and that it works, it shouldn't require any 
changes, as what you'll have when you get to school is:

internet ---- univ-network-stuff ---- m0n0 ---- PC

I think your current config is fine.  The cable modem and linksys go 
away, just plug the m0n0 into the cat5 drop in your room at school. 

Is your m0n0 WAN interface getting it's IP via DHCP?  If so, you should 
be all set.  If not, then you'll likely have to change that when you get 
there, depending on how they assign IP addresses.
