Here are the 2011 NHRA rules:
In other words, you aren't forced to put the battery in the back, but if you do you need to add the cutoff. The cutoff also MUST interrupt the charging circuit so that the truck quits running when the switch is turned off (usually done with a dual-circuit shutoff that disconnects the field/sense wire from the battery at the same time).
Other items that come to mind:
Locking transmission dipstick required 10.99 & quicker
Aftermarket axles required 10.99 & quicker - however most tracks seem to accept full floating axles in lieu of aftermarket (following common sense).
In other words, for virtually all of the trucks here they should only need a roll bar. The rollbar requirements are shown in the NHRA rulebook, but they are basically a 5-point minimum (main hoop, 2 rear braces, and one sidebar next to the driver). The part that seems trickier is how you mount it to the frame, as most truck frames don't stick out far enough towards the outside of the truck.

In other words, 10 second trucks would need a trans shield/blanket. Keep in mind that "hard" shields are only good for 5 years, and blanket-type shields are only good for 2 years.
