I would also place myself in the 'very substantial progress but not yet fully healed' camp - 9 weeks after an achilles injury.
After initial ice, ibuprofen and rest, I have done 8 weeks of eccentric heel drops (3 * 20-25 reps, twice daily, straight and bent knee) building from bodyweight to weighted rucsac (2l mineral water bottles) and currently a 60kg partner on shoulders, or a gym calf raise machine.
I have also done a lot of cross frictional massage with arnica, worn an improvised sock at night (a pair of tights..) to keep the tendon long, taken 3g daily of glucosamine, and latterly done a lot of soleus and general calf work with a foam roller.
Recently I have jogged 2-3k without problems on a number of occasions but still have 5 mins of morning stiffness. The rest of the day the tendon is rock solid.
FWIW, these are my conclusions...
1) If you are a moderately high mileage runner aged >30, you really should be using a foam roller on your calves several times a week.
2) Eccentric heel drops with increasing load are excellent to strengthen the tendon
3) All you read is correct - don't expect to run for 2-3 months. I have done plenty of cycling and swimming, both of which are OK for the tendon, even hill climbs on a bike and wall pushing from turns in the pool.
4) I find a child's rubber bouncy ball is better than the generally quoted golf ball for sole massage
