I am very new at this so bear with me

I installed alot of plugins the other day (about 3 days ago) and now when I go to install any new ones, a page comes up saying that it cant connect to my FTP. All my new plugins are in there and downloaded! It also says that the plugins are already installed in my server...I dont see them anywhere! Its driving me crazy!
I also cant figure out how to make the smiley toolbar work. They just come up with the symbol for them.
Like I said, Im new at this, so be gentle on your critisism..lol
