DNA ML Questions

We've been using Fast DNAml to do some phylogenetic trees and have some
general questions about ML algorithms in general:  Is it necessary to
bootstrap ML trees, since the ML algorithm is in itself a statistical
procedure?  Also, should we expect bootstrap values to be inherently lower
with the ML algorithm (as opposed to parsimony or distance methods)?
We've run trees on a various data sets of 37 taxa with over 2000
characters and found that the ML algorithm consistently gives us MUCH
lower bootstrap values...thanks for any and all help!
