Joanna was in KL for the 10yr coronation tourny ~8 1/2 months prior to Tyrions birth. Ergo he can be Tyrion's father.
Not conclusive evidence for Tyrion of course (there's lots more for that in this thread that I went over), but it eliminates Jaime/Cersei entirely.

His point is that anyone who has ridden a dragon has been a Targaryen (with one exception with extensive extenuating circumstances that you've actually not even talked about, but I digress.) ie. being Targ is a necessary requirement to ride a dragon and therefore to ride one proves Targ blood. Your two attempts at disproof have been:
1) Sheepstealer not being tamed - Irrelevant. He didn't claim that all dragons would be tamed by Targaryens. He said that being Targ was a requirement for riding. Two very different things.
2) Not all Targs ride dragons - Again irrelevant, as his claim was that it was necessary to be a Targ in order to ride, not that being a Targ was a guarantee to ride. Again two very different things.
To put it in more abstract terms. He claimed "p" is necessary for "q". You got that confused with p is sufficient for q. A common logical error, and something he never claimed. You thus have made two logically irrelevant arguments that have been true, but trivially true and have not actually addressed his claim. You have successfully argued that "not all dragons are ridden", and that "not all Targaryens are riders." You have not successfully argued that "not all riders are Targaryen."
