mate it comes down to what you wanna spend! call wooders and get the rugged ridge sye and tom woods driveshaft if you have money to blow, im sure there are even better sye's. but i posted a link to a budget sye and dc shaft for a solid 500bucks delivered which i installed on the weekend and im very happy with the quality...
ring wooders and he will be able to set you up with everything you need and im sure he will give you a good price too.....the 3.5: rubicon express superflex kit is a good set up all tho many decide to change out there rear springs for something diffferent as they are pretty hard and i think they sit about an inch higher then the front....i have heard of people putting the stock tj front springs into the back with their rubicon 3.5" superflex kit
you say your two main quetions are lift and sye.....if thats all you want help with then its really nothing too hard at all,
here is a good sye for you

and a good driveshaft

thats your sye sorted, or you can go get the one i got, its up to you
and for your lift

thats it, go buy some shocks, fox if you like, many run rancho 9000's or the ome, all respectable shocks, plus many more
then you will need some upper control arms so might aswell get RE to match and you will have your jeep set up on a 3.5" lift with sye and dc shaft..
now you may think its that simple but then you need to get front and rear adj panhards, extend your breathers ect ect ect
honestly man just do some searching first and then come to us with questions, were willing to help you out but not going to do everything for you!
