Hi James and welcome to the group.
I've seen Alan Doyle's work too, either on YouTube or Vimeo, and its stunning. You have to remember though that he was a professional and the work he has posted was either made for a client or something he did on the side while working for a client.
Most of your questions can be answered by doing some Google searches. I just went through this same process a few months ago. I wish there was an easy (hence CHEAP) way of getting Super 8 footage onto a PC, editing, and then playing it on the big flat screen TV. Doesn't seem to though, or else I'm not finding it.
