A little help with some questions about Speedotron Brownline for small product

[beachrat]

I started out learning to light with speedlights thinking that portability was going to be a priority,but it turns out it's not.
Wanting to give bigger lights a try,I picked up a couple of old White Lightning coffee cans and realized I liked the bigger stuff and want to start setting up a pack and head kit.
Considering that what I've been using is more than powerful enough(the WL rarely leaves 1/3 power),I'm thinking that a D402 would work out real well.
I'm just not too sure about which heads I want to go with.
Am I correct in thinking that the M11 is the most versatile head as far as interchangeable modifiers go?
Would a couple of those,an M90 and an M3W be a good way to start?
Also,all of the Speedotron packs that I've seen had a HH synch port. Would I just need a short HH to mini jack cord to go wireless?

TIA
