"1) How does everyone build their circuit cards and why do you pick your method?(eyelets, turret lugs, nails)"
 
 
The final choice is preference/convienence. I've used both eyelets and turrets and prefer eyelets. To me they are just easier to work with. Drilling for turrets without a drill press, unless you have a keen eye its hard to get the turrets to stand perfectly straight.  
 
I'm going with turrets on my next project that is starting to form. Space is kinda at a premium so I'm thinking it will work out better for me. Normally it's eyelets.

"2) What order do you typically install things in the chassis in? (sockets and heater wire, xformers, etc.)"
 
 
From paper it goes on the chassis from the ground up. Normally punch for the sockets and mount the transformers. Build up the board and lay that in the chassis and look for conflicts with it's placement and where the pots/jacks/sockets will go. If all looks good I then mount the board and again check for problem areas. Then I pretty much strip the chassis and drill all the pot/jack locations.  
 
When everything is drilled and deburred. I mount all the components again and look for trouble areas. At that point I again pull the board and wire up the power supply, and any of the non board wiring I can. At that stage the board is mounted a couple of hundred times looking for conflicts with unboard runs etc...  
 
Heaters get hooked up depending on the way I run them. Marshall style tucked into the back of the chassis they get wired up pretty early. Fender style over the sockets--last.  
 
When everything that can be wired without the circuit board is done. It's mounted for the final time and wired up---and hopefully everything works out as planned.  
 
I do tests of the power supply along the way to make sure I dont' mess up anything early. Zip tie all wires together that I can get away with and tuck everything neatly away.  
 
One thing to mention, if your moutning a custom chassis to a custom box I would mount it up first before adding 30pds to your chassis and trying to figure it out.  
 
best of luck
