As an out of work, hifi enthuiast who's been in and out of credit card debt, I'd highly recommend the transfer, closing the old cards, and working now. Make enough cash to get by and only use the credit if you get into a jam where you will not be able to work. (Car broken, etc.)
I personally never have and never will wait tables but, I've been a meatman, salesman, warehouse guy, stage manager, photographer, computer guy, etc.. whatever it took that seemed mildy interesting in some way.
I think if you try to find something that is slightly related to law, you'd be better off than buying anything. (Unless you're trading your gear) The feeling I'd get from buying new gear would cause grief and work against me finding a job.
If you're selling gear and then using the proceeds for new stuff and have a net zero, then I think it's a good way to stay busy. Just make sure you get the money first. That's what I'm doing now. I'm selling speakers and pre to get new speakers and pre. It's tough to ride the line of 'staying busy' and 'obsessing over something else so I don't have to think about the real problem'.... try not to let that happen.
Best of luck!
