Advice needed, NOW!

So, how exactly do you go about approaching an academic that you admire and say "Can I be your PhD student? Please?".

Apparently there exists some sort of college academic scholarship which you have to apply for by 29th June, and apparently the person I want to work with isn't going to be around for most of this week, so I need to talk to him asap. Argh. I'd been hoping to have stalkedresearched his entire paper output on the Web of Science and read all of them before going to see him.

Well, I've arranged a meeting for 4pm tomorrow and I'll spend as much of the morning as exists in the British Library.
