I recommend a hand throttle control. It helps ALOT imo. If not and you have to do some heavy winching you will have to sit in the front seat and apply some throttle manually which sucks especially when you're by yourself and you have to be outside the jeep.
Also just like the poster before me, gloves are absolutely necessary and I always have a flashlight too just in case you get caught out at night.
As far as what to do about the rake, I don't have a lift but I have a 1.75 spacer on the front of mine and it sits slightly unlevel so you might think about trying a RC 4 inch coil for the front, I bet that would get you level.
