Correct.

Correct.  In terms of the amount of space consumed, maintenance doesn't change 
very much.

Neither of those are really important to recovering a broken LVM.  The stuff in 
/, and /etc are.

No, you can't (easily) separate /etc from /.  It can be done, but it's not 
really recommended for anyone that is relatively new to Linux.  Keep, /bin, 
/etc,, /lib, /lib64, /root, /sbin, and optionally /boot in the root file 
system.  Everything else can and should be broken out into a separate file 
system, preferable on LVM LVs.
