I have just the proper tool for test FETs. It will tell all of that and even if it is an enhanced mode FET. They use those primarily in switching applications. If you have a fet with just a little too much gate capacitance there are ways to fix that. Sorry can't get the formula to appear properly

NKA
C= -------
D
N is the number of plates
K is the dielectric constant
A is the area of the plates
______________________
D is the distance
between the plates
This is the simplified capacitance formula.
