Pete, I think youre leaning in the right direction.

I remember when 74Duster360 stroked his 360 and made NO OTHER changes. I couldn't believe the attitude change in the motor. The 360 with 244@.050 hughes solid cam and 10.8:1 compression wanted to be tached to 6400. The 408 was down to 10:1, made "big blockish" torque (Hi Ryan ) and now was shifted at 6000 rpm at the track for best e.t.. This car had the worst hacked iron heads you will ever see. They were junk. The car was a few hundred pounds lighter than yours and ran more gear but went 11.70's all day.

As much as you street drive the car, and for what your planning on doing I would definately go the stroker route. You wont be spinning it hard so follow Ryans advice and save the money on the internal balance job. Keep the 3.55's until you can find someone to swap you some 3.91's or a good deal on a chunk comes around. I'd look into something like the Comp XE284 cam or maybe the Hughes 3844 hydraulic which is 238/244 @.050 and 536/540 lift or something like that.
