I'd just install the additional soffit vents and be done with it. If,
on the other hand, you were to install ridge vents and soffit vents,
then you'd want to close off the gable vents because the ridge vents
draw from the source closest to their level.


WRONG. You can't have "too much" venting. Leave the gable vents open--
they will help.


Do a little more reading on the subject. While it is true that you
can't have too much properly designed ventilation, the key is
"properly designed."

For example, if you have ridge vents, it is best to close off all
other vents except the soffit vents, if you want air to be drawn in
from the soffits. Why? Has to do with fluid dynamics. There are plenty
of sites where you can read up on the issues involved.

Here's one that does a good job if discussing many of the factors
involved:

Have a good read...
