tire and gear combo sounds right.
sounds like the turbo just isn't coming in quick enough, you're not launching with enough boost, or you're not launching hard enough in the engines power band.
converter might need to be a little bit looser if you're launching around 3200rpms, i bet closer to 4k would help.
like my suspension guy said, "throw some damn power at it off the line"
the most common gear tire combo's are fairly close to what you have for example.
30" and 3.73
28" and 3.42
33" and 3.55
28" and 3.23
i've seen trucks with all those combos work really similar to one another.
4.10's seem to work well too.
probably not gear and tire related, and you said the rear suspension is fine.
