It is all in how much you think your truck can take. If you think you are going to be beating the hell out of it on a regular basis, and do not want to keep spending money on replacing plastic, then there are places on the truck ideally suited for an upgrade to a metal part.
Chassis braces, bulkheads, bulkhead braces, and bumpers are all good things to upgrade to a metal component. I say metal, because some can afford to lay out the dough for titanium (which is way better than aluminum). You want to keep the bumper brakets plastic for the reasons mentioned above.
Suspension is another area that can afford some upgrades. A nice set of all metal shocks is a great upgrade. There are a number of quality shocks out there. You can use the search function of this site to read through several discussions about them. Titanium turnbuckles are also another great hop-up. If you get them, get a beefier rod end. You can go with either RPM (plastic) shock towers or upgrade to a good aluminum set. The plastic will give a little on the big air, but the aluminum gives a rock solid base for the shocks to work from.
Areas that are a wash when it comes to metal.
Skid plates. Do not get aluminum; if you must get metal, go straight to titanium. The aluminum skids will give you more fits for having to spend down time reshaping them than they are worth (the exception being the center skid...aluminum, titanium, plastic...all work well for the center skid). I run the stock plastic skid plates. They are flexible and inexpensive to replace if they get broken.
A-arms. Aluminum a-arms are just begging to be replaced as expensively as possible. The problem with aluminum a-arms is that they do not reshape so easily, and they are expensive to replace. You are better off sticking with a quality plastic set (RPM). You could upgrade the upper a-arms to metal (as I did), but that is a matter of preference. The ones that you need to watch are those closest to the ground (and therefore more prone to contact with objects on the ground).
Why does everyone push the RPM button when it comes to plastic parts? Simple, they are near indestructible. If you manage to break one, then send it back to RPM and they replace it no questions asked.
Anyway, I think I have used up my dime on this one...
