The funny bump/weave pattern of wear on you OEM tires is common, some here call it feathering. Running slightly higher tire pressures may alleviate it to some extent, but it seems an inevitable thing with the Bridgestones. By the time I changed my first pair of BT020's (9,000 miles!) they were worn as you describe, with the back so square I could feel it 'fall over' as I tipped into a turn. New BT021's cured that.
I'll be anxious to hear how your Avons wear.
