you are visiting the university, there are ALWAYS course for foreigners! these courses are for students for free, so JOIN ONE!!! otherwise you may pick up some finnish, but without a teacher you nearly never learn it...

there are so many good websites to learn Finnish, you can start with these two http://uusikielemme.fi http://www.ielanguages.com/finnish.html and I would recommend you to have Leila White - Suomen kielioppia ulkomaalaisille, this book might good to start with. And I totally agree with Finnish girl, you really need to study hard but as you will have a chance to interact with the native speakers so you can learn faster. Good luck!

yes, but u would probably have to work really hard.
