webbo, good to hear you're close to getting the green light. From your fit-club updates, you're cycling 40 miles and doing plyometrics so probably ready for some gentle climbing. You could show your physio. some climbing videos illustrating the sort of thing you have in mind. S/he should then have a better idea of what you're letting yourself in for.
I'd think the most important thing to avoid is any unexpected shock loading such as landing from any height on your toes, so no bouldering at the moment. You also need to avoid clipping your foot on any protruding holds if you fall off.
You might be quite statically strong from the fingerboarding but rather out of practice moving. This is a slightly risky time for injuring something else, so ease into things slowly (statement of the obvious...).
I would suggest top-roping gently overhanging lines. Steep enough to fall clear of the wall but not so steep you need to claw in with your toes. Avoid high steps, long stretches, and any creative footwork. Keep it all basic at this stage.
