I dont fully understand what your question is but what you should change is to first select your hands according to the position you are at, you can find a lot of sheets with with which range you should play from which position, here is one post i find really useful, you can also check the whole tread
plus search the PSO for their starting hands, there is downloadable pdf version.
Now about your position when table selecting i again didnt understand how you select your spot but here is how you should do it according to harrington
bigstack loose player to your right and shortstack tight player to your left
About betting pattern you'll want all your bets to be the same size no madder what hand you have, that means that you should open with same size no mader you have AA or 89s that means betting pattern, i dont know what limits you play or is it cash or mtt but ill assume that it is micros and there you rarely find a player who would figure out your betting pattern, so it cant be the problem there, your biggest problem probably is playing to loose passive and oop and you might overestimate your hand strength and dont give credit to your opponents enough.
This is the best i could from the little info you gave, hope this helps please hit up with additional info or more questions if you need more help...
