well, first of all "weak" means nothing quantitative. It's a strictly better bet size because it folds out a similar range but costs half the price, weak and strong have nothing to do with it, they're just cop out terms like "I don't minbet". A minbet here is half the pot, which is a very useful betsize, avoiding it because solely because you cannot bet less than half pot in this spot is, as I said before, stupid.
9 tabling husngs, especially 2$ ones, is massively -EV. You're leaking in nine different tables at the same time (You yourself said you aren't even able to adjust your betsizing!). Most 2p2 people play 1 or 2 tables. When learning (ie playing micro stakes) 1 table let's you learn more and achieve a higher roi to let you move up faster so that you're not playing for highly raked cheesburgers anymore. Again, it's just stupid.
I'm not going to go into the rest of your post, all I'll say is you have a lot to learn so be very open to criticism. Read a lot of the stickies in the FAQ. Post more hands (I'm certainly not trying to discourage you!). Think not just about poker but also about how you're thinking about poker and you'll be able to play achieve a higher level of thought process (and by transitivity, a more profitable poker game). Always be able and willing to adjust.
