A few simple customizations to wordpress theme

a few simple customizations please. They are easy, I just dont have the time 1. I am using the social share boost plugin, but I cant seem to get the social buttons to work for my image posts. I want the social buttons below my image. The plugin says shortcode is an option, but I cant get it to work. 2. The plugin also seems to have inserted the text "tweet" into the entry meta section on the homepage. I I have created can make this text disappear with firebug, but cant figure out what to change to fix it in my files 3. Lastly I have created a tag/topic page, but or some reason the let sidebar is showing on the page template...must be pulling it from theme files or something. I do not want the left sidebar there also I need the number of tags displayed on page to be 50 (super simple fix, but I dont want to search for the variable to change)
