Rick,
The Dept of Western Virginia contained units other than Virginia Units in Sept. 1862. There were also units from Kentucky, Tennessee, and Georgia. But if you are only interested in the Virginia outfits, here are some of them. I'm sure there are more but these are off the top of my head.
INFANTRY REGIMENTS
22nd, 29th, 36th, 45th, 50th, 51st, 54th, 60th, 63rd
INFANTRY BATTALIONS
21st, 23rd, 26th, 29th, 30th(Sharpshooters)
CAVALRY REGIMENTS
8th, 14th
CAVALRY BATTALIONS
Caldwell's, Ferguson's, Baldwin's
ARTILLERY
Chapman's(Monroe "Dixie") Battery, Bryan's( Monroe, "Lewisburg") Battery, Lowry's(Centreville Rifles) Battery, Walker's(Richmond Otey) Battery, Dickenson's(Ringold) Battery, Davidson's(Lynchburg) Battery, Jeffress's(Nottoway) Battery
As I previously stated there are other units, but these come to mind at this time.
