Re: Headphone Question.....
What you can do is run a line out from your amp, into your stereo amp (via a connecting lead - you can make / maybe buy one with the right connectors), then use the headphone jack on the stereo.
I ran my guitar through the stereo when I was a young kid with no amp.
You can also pick up really cheap headphone practice units from Nobels I think. Doubt they sound great, but may be an option.
