TacoWorld... I need your wisdom

Let me start off by saying I've spent multiple hours after work for the past few weeks reading old threads etc etc until my ape brain became soggy. There is a lot of variance in opinions, as one would expect, and I would appreciate current opinions and advice from minds in this moment in time. So Thank You to anyone who is willing to repeat themselves on the subject, I appreciate you...

I got this truck 6 months ago (completely stock from my step dad, apart from him putting on the trd pro wheels, husky floor mats and the toneau) and I've initially just put 5100's up front (2 inches of lift) with a 1 inch block in the back so it didn't feel like (height wise) I was driving a car. Well, I'm tired of this shit already. I don't have bundles of $$$ and have other things to invest in so fox/icon etc will not be an option, nor is it needed. I can do springs, rear struts and possibly new leaf packs if not just the AAL. I live out in the sticks, go off road and would like to do more moderate off roading when this thing becomes more capable. I absolutely do not want to have to upgrade the UCA's as a good pair is crazy expensive in Canada... a grand cad for spc' which get plenty of shit reviews - 1,200-1,400 for the good stuff what the fuck!?

Regarding Weight: The only thing in this trucks future armour wise are sliders. It will most likely be towing a 15'-16' fibreglass or aluminum boat with 70+8 outboards on the back next summer. The misses and I would also like a RTT down the line but that's most likely 2+ years away. If going with all new leaf packs, as opposed to an AAL, better serves the truck in the near future then I'm willing to make the investment now.

Regarding Aesthetics: The truck 'looks' good now, however if I was to do the most basic mod right now it would be replacing the 1'' block with a 1.5'' AAL. When I tow the boat I don't want it sagging to shit, the roads are gnarly around here, but if there is a bit of a droop I'm ok with that.

So the conundrum here is what height am I going to get from this or that, how much is it going to settle. Is it going to ride stiff? I'm not too worried about this one. As long as nothing is preloaded I feel fine about it. I treat my vehicles well so I want longevity with my purchases.

My thoughts are getting the 885's up front so struts can be set at 0. And then most likely the medium duty dakars with 5100's rear?
Will 5100's in the back be long enough? I've read a few times they won't.
Will the Dakar's put the back end too high for what I'd ideally like 'looks' wise?
Will taking out the overload spring in the Dakar's compromise the integrity of the pack? either now or in the future?
Should I just dump my girlfriend and buy a new Supra?

These are questions I need answers to.
