"mv" command > Proper regex to move SOME files? Does linux / ubuntu let you use regex and wildcards?

So here's the deal, I have a bunch of pictures...

product1_lrg.jpg
product1_01_lrg.jpg
product1_02_lrg.jpg
product1_03_lrg.jpg
product1_04_lrg.jpg
product1_05_lrg.jpg
product1_06_lrg.jpg

product2_lrg.jpg
product2_01_lrg.jpg
product2_02_lrg.jpg
product2_03_lrg.jpg

my products all follow the same naming scheme, I would like to rename the first product of each group to "productX_00_lrg.jpg" instead of "productX_lrg.jpg"

I was thinking if there is an easy regex way to move the "productX_lrg.jpg" files into another folder I could make a script in OO Calc to rename them, but the hard part is moving only the "productX_lrg.jpg" files without moving the others...

What I need is a way to move all files that end with an underscrore then 2 numbers another underscore then "lrg.jpg" into a separate directory.
