A: OK Double 2by is 3 inches plus 3 1/2 inches is 6 1/2 inches I think a 7 inch will do the job. Fastenmaster has documentation that specs the sizes on their website. https://www.fastenmaster.com/
A: This works great for railing posts, 9.5" bolt designed for connecting 6x6 to 2x lumber, so it should work in your case if you want to connect 6x6 to the rim joist (opposite of the house) and/or floor joists. If plan on notching your post then get 8" bolts, in case you going to have to double your joists or add backing blocks then get also 12" bolts. We usually use 4 bolts per post (2 through perimeter and two through floor joists).
A: The Thru lock hex head device is a replacement for half inch bolts,washers and nuts. You don't have to pre drill for any of your connectors. The Thru Locks have a self drawing screw head that is tightened by threading itself into the pointed locking head. You have to use the correct length of Thru Lock for the overall thickness of the joists and posts being connected, or installed. The thru locks come in various lengths. Hopefully, this is a clear enough explanation.
A: These "Thrulok" bolts come in various sizes, you can connect 6x6 and 2x with it, also if you need to notch your post, there is a smaller size, or if you going with double 2x - there's longer bolt available. In regards to your question about connection of 6x6 and 2x ledger - it seems like it would be a bit hard to do as you need access from both sides of the lumber you are connecting, so you either need to get them connected together prior to attaching your ledger board or use longer bolt to go through your ledger and whatever lumber you have behind it...
