I dont have a whole bunch of wisdom to pass on except to enjoy your summer - med school will be here before you know it.
Also, I think I have said this before dont get too caught up in being a gunner. Everyone will do just fine, it can get very stressful diving into anatomy and everyone is so stressed out about doing well that it can become overwhelming very fast. You got into med school for a reason (b/c you are very smart and they know you can handle the work) so you will do just fine without taking yourself too seriously and loosing handle of your life. I honestly found that I did the same grade wise if I studied for six hours or three and I was much happier only studying three to four hours a day (and my boyfriend would agree).
As far as furniture - check out this site:

We bought a sofa, chair and ottoman and love it. I was very skeptical at first, furniture in a box sounds kind of cheesy but when we got the pieces and put them together it turned out very nice. And for a decent price too. Sofas can be very expensive, and we didn't really like the idea of getting used furniture (unless it came from people we know). I loved the idea of being able to change colors without having to buy all new sofas ... and slip covers are worthless b/c they always fall off and look pretty crappy. Plus, you can buy replacement pieces if you need them.
Craigs list is also a great place to look for furniture and pretty much anything else you need. Can find lots of cheap stuff and you can use the Baltimore search to find local sellers:
http://baltimore.craigslist.org. You can do the same thing on ebay - I don't like ebay as much though b/c things tend to be much more expensive. Just my two cents though.
The gym is alright - its free so that is the one thing in its favor. It is above the Pratt street garage and there isn't any air conditioning which makes it very hot during the summer. I have not used it in two years though so it might have changed (we have a gym in the apartment we live at which I use instead). They have all sorts of equipment in the Pratt St gym and there are BB leagues and exercise classes.
There are plenty of class events most will be planned by your class officers so it really depends on those people what kind of things will be arranged. The alumni office also does a lot of events
believe me you will have many chances to hang out with your classmates and the other classes too. Next year will be quite fun our class is the bicentennial (2007) and there is supposed to be quite a deal of parties and events to celebrate. I do not have all the details but, from what I have heard the week of our graduation, there is supposed to be quite a deal of celebrations and gatherings. Believe me; you will have plenty of things planned for you during orientation too.
It can be a week of partying if you want plus, you will be meeting all of your classmates and it is quite a fun time!
