308 clutch replacement

Ginas' wheels are off for repaint, so now is a good time to change the clutch...... While she is on the axle stands, I thought it is time too to repaint the stainless exhaust which is looking a little tired. To remove the exhaust silencer box, i have to either unbolt the drive-shaft, remove the bottom wishbone bolt at the hub end, or, the lower wishbone chassis end bolts - this will allow the exhaust pipe to pass between the lower wishbone and the drive shaft.....anybody know which is the easier option ?
Any suggestions re: black exhaust paint ?
The distributor is readily accessible, so new points will be going in and similarly the fuel filter will be changed.......anybody any further suggestions ?
The oil and filter will be changed, but i am a little unsure whilst she is on axle stands (engine warm-up).......anybody any horror stories regarding cars rolling off the four axle stands ?
Many thanks in anticipation
