First... wait for it to heal. Then, it is my understanding that connective tissue (tendons and ligaments) are best strengthened with lightweight, high rep exercises. This is because they grow at a much slower rate than muscle, and the lighter weight will sort of compensate for that.
However, nothing will stress you body (and cause growth and strengthening) like heavy weights and low reps: you'll increase tendon strength, muscle strength, bone density, ligament strength. But heavy lifting has considerably more risks, ESPECIALLY if you're comming back from an injury. That being said, you can lift heavy for your whole life without incident if you lift properly.
Basically, let it heal properly, then rehab it, then do some high rep resistance work (15-20 reps) for a couple months (remember, burning in muscles = ok. sharp pain in joints and at insertion points = bad and stop what you're doing or lighten the weight until it doesn't happen) and then move on the bigger (and heavier) things.
By stregthening your muscles, you also strengthen your tendons. That's why roids are so bad for you. B/c they build your muscles faster than your tendons and you start tearing stuff. Resistance training will strengthen tendons.
I don't know that strengthening a tendon will aid in any force producing technique, but it will aid in injury prevention. Tendons are what hold muscles to bone. Maybe if you could surgically alter your tendon insertion points to create a better mechanical advantage, but I don't think that's feasible.
