You don't have to worry about any of those things, if the suspension is stock.
I just checked what shocks i bought for mine.
In the front they where 14.82"-24.84" (sky N8027)
and the rear was 17.32"-29.83" (sky N8038)
Mine is lifted slightly (2"-4" not sure exactly)
And I measured that the shocks couldn't bottom out.
I disconnected the shocks and used the front-loader on my tractor to check flex and drop.

So you don't have to worry about bottoming out those you mentioned.
Damn, now you got my head spinning, I think I'll go ahead and order a set of bilsteins as well.
