I don't want a "hopefully". I want a definitely. Did you get clearance from your doctor to begin exercising at 100%? If not, what restrictions did they say? Collarbones are not something you want to screw with, since they're in a perfect place to potentially screw with your shoulder, chest, and back exercises in the future.
Aside from that...
What is your primary goal? Building muscle, gaining strength, losing fat, preparing for sport?
Check http://www.craigslist.org for your local area to see if anyone nearby is getting rid of any equipment. I know a few people who filled a large majority of their home gyms this way.
If equipment is limited, you'll need to get comfortable with bodyweight exercises. Depending on your shoulder/collarbone health, all variations of push-ups, pull-ups/chin-ups, squats, lunges, etc. You can find some bodyweight exercises/routines by doing a search here on T-Nation. Rosstraining.com and Trainforstrength.com also have a bunch of bodyweight info.
In short, yes, you have plenty of options available to get some kickass workouts. Get back to us with your goals, and we can figure something out.
