I'd like to add a subpanel for a workshop and am wondering if it absolutely
has to be wired off of a breaker in the main box or if it can be wired from
the meter (i.e., can I have two main panels).

Not and meet Code.

I realize this is atypical,
but I have the following to deal with:
1) My meter is on the wall of my workshop, whereas my breaker box is in
the basement on an interior wall on the other side of the house. Not only
would it be very difficult to fish but it seems inefficient to run feeder
all the way back to the workshop.

There's already a feeder going from the meter to the main panel. You could
install a new main panel in the workshop, and convert the existing main panel
to a subpanel fed from the new main panel, using the existing feeder.

2) My house has 150 amp service and I need 100 in my workshop.

Why 100A in the workshop? What are you running in there, that you require such
heavy service to the shop?
