With regards to travelling about, theres this young chap who sings and plays guitar a bit.
Think his name is Martin Carthy, or something?
He travels virtually exclusively on Public Transport, and seems to be doing alright!
Mind you I understand that it's something of a military excersise to achieve.

I met him a month ago at a festival in Preston Lancs, and he'd just played Glastonstbury festival the night before.

He got up only 1 hour late, and if you know how rubbish the West Line rail service is on a Sunday, I'd call it a fairly major miracle!

Good Luck with the project
