Ahh, I remember doing a project like that in highschool. My 77 Power Wagon. It still sits in the garage half torn apart

Anyway, it sounds like you are just building a multi putpose truck, that will be alittle good at everything, and not specialized at any one thing.
Honesty, by best piece of advice is to drive the truck and see what you dont like. It probabally wont take long to see how the truck works well in one area, and is worthless in another. Honestly, what works for me, may not work well for you.
As far as a cheap suspension, its hard to go wrong with the rear sup front/chevys combo. Although, I did the math on how much it cost to put mine together, and it is close to 1k installed. Sure its alot, but for how I use my truck, its perfect. (Lots of time on trails int he sierra nevada's, Hollister hills, highway time drivign to and from, and still being able to go to the lumber yard and load it up. )
If you want me to go over every step of my build, I can, but I think it would be better for you to learn on your own.
