I'm new to Commuting, not to biking.

Gas Prices, need weight loss, and use for a new hobby is why I want to Commute.

But I need some help with the bike, bike setup and any other things you people can.

Me and my ride to school:
220, 6'
Hate flats
I know bike tech and work on my own bikes.
Like go fast, go fast, go fast, go fast
I have a older 10 speed, trying to buy a 70's Raleigh trans-continental at the moment.
My path is: 20% busy road, 80% bike/walking path

i need some help with the tyre set up, for no flats, a rack with some panniers, locks, and any tips and tricks that could help me.

And I have around $1000 to spend, but cheaper would be better.


Thank you in advance
