From what it sounds like you need to buy a car. If you plan on doing all of that in a suburban you probably need to rethink that. Suburbans are not a light vehicle, and most of what you are wanting to do is just asking for trouble. As for what you are wanting to do yes a NV4500 will hold up. Clutch dumping will more than likely depend on the clutch you use, but you will more than likely break something or need to replace your clutch a lot. As for power shifting, the nv4500 is a truck transmission. You wont be power shifting with one of those. So like I said if you want to be doing all of that you are better off finding a car with a manual transmission.
