From an on a budget person to another on a budget person:
An inexpensive netbook with give you some internet access on a budget price.
As for surveying, unless where you keep her doesn't require insurance, you may have to fork out the dough anyway. On a 30' boat it shouldn't cost an arm and a leg and certainly less than most anything you'll have to get to get her in shape anyway. Assuming she needs more than Lysol, of course.
Find a good surveyor who'll happily tell you what he/she is doing and why and what the results mean and/or how to address them and that $300 or so bucks becomes a great and thorough introduction to your new purchase, even if she was cheap to begin with.
Good luck with your adventure!
