will i be able to pick what bomb drops first if i have different bombs loaded?

No. This is up to the A/Cs class for sure.
What the Weapon Control Mod does is to let you drop bombs at a time, but the order of the bombs is the one set in the A/C class, there's no chance to modify this from another class outside of the A/C.
Unfortunately that's one of the common mistakes modders make: They count the number of bombs, rockets or whatever ordnance else they applied to the A/C in "readers" direction from outer left wing to inner left wing followed by inner right wing to outer right wing.
An A/C from aft view will drop bombs hence in this order (assumed there are 4 bombs under each wing):

Code:

1  2  3  4         5  6  7  8

Whereas of course the better drop order would be:

Code:

1  3  5  7         8  6  4  2

Or even much better:

Code:

1  2  3  4         4  3  2  1

Or any similar kind. Unfortunately, as stated above, this requires the A/C class itself to be fine tuned.
