Sloppy rear end

Now that I have your attention.

I got an 05 prerunner that has the 3 leaf pack and it's real mushy, sloppy and bottoms out alot. I got some Icons and TC UCA's up front and now is time to fix the rear. I have tried to get the TSB done but im out of warranty by years and miles.
So what kind of leafs or AAL are good? I could go up an inch or so from the ride height im at on the rear, fronts are set at 2.5" and I might lower them to 2" as I sag about an inch in the back. Maybe something to take out the axle wrap and also the bounce while im on the freeway?
I also replaced the shocks in the rear with some monroe reflex or something like that a year ago, its what the parts shop said to use.
Anyways, they will probably be tossed into the garbage and I will find something to go with my new leafs or AAL if that will fix it.
any suggestions? anyone replaced their rears yet?

 

Here's a little something to check out.

or the (OMG!!) 10 leaf deaver springs?? are these super stiff or what?
and what about rear shocks I don't necessarily have to go cheap.
The 5100's are ok, but maybe theres something better? RR ?fox. icon??
