Braided lines are definitely a plus (and cheap too), then I would change the pads for something you know to be decent. If the discs are okay then leave them be: My current preference is to use reasonably cheap discs and spend the cash on the pads instead. Obvs if you have the money then get some awesome discs as well, but personally I feel you see more benefit from pads than discs pound for pound.
In terms of pads, I'd go for the Performance Friction 01 pads on the front and their Z-rated pads on the back. I've had personal experience with these and have found nothing better on road and track, although please check they've not updated their part codes in the last few years!
And I really wouldn't worry about putting the 'closed roads' thing on here, no-one's fooled for a minute Just put 'repeated high speed stops' or something equally vague but informative, as at least that way you're not leaving yourself open for prosecution as well as a telling off from the mods
