Of course the best answer might depend on where you are and the species
but-

There was a discussion on this subject here about a month ago. Most
foresters probably agree it's a good idea to prune, but the rate of
return on your investment is debatable. But only prune those trees
likely to ramain to full rotation.

It's OK to prune live branches, but a good general rule is to leave
about 40% of the height of the tree in live crown- at least in
Massachusetts; elsewhere I'm not sure what the rule is.

Almost any kind of prunning tools will be OK. I use a very small chain
saw on the lower branches and a series of pole saws up to 17'.

I don't think this is critical.
