In depth Help Needed

Is there an in depth tutorial on OD Plus?  I just found out that a folder was installed in My Documents to hold backgrounds, etc.  I have been downloading and putting items in the programs folder/stardock object dock...etc..  I get very confused where to put things when there are tabbed, not tabbed, flyouts, etc  mixed a file package.  Where do separate icons go?  I am so confused.  I will uninstall and start over with new downloads as long as I know the proper places to put things.  HELP!!!!!!!!
