LVM on top of MD works very well, I'm using it on all my boxes with soft
RAID. (MD == multiple discs == linux soft raid)

dooing MD on top of LVM is possible too, but makes no scense (IMHO)

OTOH if you just want one big partition (3x160GB) than there is no need
for LVM.

No, MD will do

yes, first RAID than LVM, no problems to be expected.

No
