1. BH-40 LR II: Mid-sized ballhead w/ AS II
Considering the BH-40 with LRII is the same price as the Markins Q10, I would go with the RRS. 100lbs load rating is just marketing, few setups in the world weigh that much and RRS is purposely conservative with their load ratings (like the TQC-14 holding the owner of RRS as he swings from the apex, it has a 25lb load rating). There are many more things to consider than load ratings like ergonomics, feel and operation of the main locking knob, choice and variety of clamps (very important) and overwhelming customer satisfaction to name a few. I have the BH-55 and BH-40 and love them both equally.
With the 70-200, yes you will want to get an arca-swiss style plate for the tripod collar, as the lens balances around that point. It would not be a good idea to mount the camera body to the ball-head with that lens attached, you want to mount the lens with tripod collar and plate on the ball-head. The RRS plate for the 70-200 f/2.8L IS II is the L84 plate.
Regarding panoramas, you can do panoramas with these heads, provided the subject is far away, but for real panoramas in order to avoid parallax issues you will want to use a nodal rail and locate the no-parallax-point of the lens (and use the panning clamp, not the panning base of the ball-head), multi-row panoramas will require even more equipment (and measuring).
If everything else is RRS, then that's another good reason to go with the RRS ball-head as well.
