First of all, you should finish your bachelor in comp. science, unless you really really hate it..
1) Here in debrecen we have class sizes of about 30~40 people in first year, I think there are about 400 medical students and maybe 300 dentistry for first year, saw those numbers somewhere.. can't remember where though so don't take my word 100%.
2) You have access to them yes, are they willing to borrow you their time? 9 out of 10 times, nope, you'll even get yelled at for attempting to waste their time. On a positive note, you can always send an e-mail! If they answer it.. well, that's another story..
You can always send a mail to PhD students, they're much more helpful, they know a bit less but they're going to help you as much as they can!
3) Yeah there is wireless internet "on campus", by that I mean, in the library, in LSB building (main science building) and in T-building (where you'll have your labs), will it be fast? Nope.
4) Pubmed.. that's it I think.
Also, avoid doing a year of wasted "college" that's not college, it's just a way to fool gullible people into wasting money, you'll do high school "O - level" stuff, they don't expect you to understand your science anyhow.. just memorize. Aim for getting in directly into medicine, study and memorize stuff, no need to waste money on their "preparation courses" seriously, don't!
Advice for a better place..? Where are you from? If you're from the EU, learn dutch / german / spanish / french / any western eu language while doing you Bachelor and try to study there, if you are bilingual now, in two "latin" languages, then you're going to have an easy time learning the language.
If you really have to do medicine now (my case) then try to get into another country like england or malta where tuition is free for EU members, or just come and suffer here in Hungary.
*ps, your math skills, or the "logical thinking" will help you here with first year, so again, no preparation 1 year course please
