5$ Bubble play is still killing me

My short handed play has really been holding me back as of late. I wondered if you guys knew of any good posts or anything to help me out. Until then would you please take a look at these hands and tell me if I did the right thing? Any help or comments are greatly appreciated. I tried to post the results in white but I am not sure if it is working or not, none the less the results are at the bottom of the page, hopefully in white.
