Being new I have been looking all over CB Nation trying to figure out where I should ask my questions.  So question 1 is where do I enter my questions?

I purchased a new 3 string fretted CBG over eBay and am attempting to teach myself to play.  I am having a terrible time trying to play bar chords.  I cannot get all 3 strings to sound using 1 finger.Any suggestions?

I do not have much sustain.  I am playing thru a acoustic 10w power amp.  Not sure if it is my cbg, my amp or just me.  Suggestions?

I have a terrible time when I attempt to use a slide.  I have a brass metal one and a all glass one.  When I try to slide up the neck the fret's sound like a motor boat.  Trying to bar using a slide sounds horrible.  lots of fret rattle.  I wonder if my strings are too close to the frets.  I have thought about putting something under the nutt to raise the strings.  Is this a good idea, or would I just be making many more headache's than I want to get into?  Help please.
