Some questions - Loctite?, grease on discs&what axle gre

1. Should I loctite the handlebar bolts and disc bolts etc. that the manual says I should? Or is it safe to race with out it if I check them often? They will probably come off and on a fair bit....
2. I have gotten some grease etc on the front discs, what is safe to use to get it off? Metho? I will give them a light sanding afterwards too.
3. What grease is good to use on the axles, and is readily available etc.? And do ya just whack a whole bunch of the stuff in there? They seem pretty dry ATM.
Thanks.
