It sounds like you're on the right track though you might consider adding more ATGs into your force mix.

Shermans are just around the corner and that will, temporarily, turn the tide for the armor match up. Otherwise the only thing I didn't see listed in your tactics is the use of artillery to breakup the enemy tank formations and separate them from their supporting infantry, but I suppose you're doing that along with using your ATGs in conjunction with your tanks and infantry to deal with the panzers you isolate.

Later in the war though you'll run into this situation again when Tigers, and later Panthers, start appearing along with long gun MkIVs. It was pretty much a fact of life for the western allies.
