The bolts for the pressure plate should come as part of the clutch kit. As far as i'm aware they are not strech bolts (TTY).
However the bolts that hold the flywheel to the crankshaft should be replaced everytime as they are stretch bolts.
Bolts for holding Clutch pressure plate to flywheel (1.8t 02m guessing its an LCR by the photo) = N 90308605 can't remember how many you need, i think 6 but i would order 10 just incase as they will be around 30 pence each.
Bolts for Flywheel to Crank = N 90665001 (for BAM, ARY, AUQ, AMK) x 6 required.... About £1.50 each
Hope this is what your after
