how much travel should I be getting on both the 5th coil and the 6th coil. Also what is the rate spring that rocket suggest for the 6th coil? Ive been lacking a little forward traction and am looking into the lift bar area to make sure everything is working properly

Typically a 6th coil rate is around 300 to 400, but you might see a few cars have 600 from years ago

Typically you will see around 1 to 1.5" travel out of the 6th coil but going to depend on rate and how hard you are on the brakes at times

5th coil travel will depend on rate, it's length away from axle centerline, HP and traction available. Up to 4" of travel can be see at times when it's hammer down and you have a 900HP engine. Something like a crate you may be as low as 2"
