Westin makes a nice grille guard, the sportsman series Linky for Westin
I have one on my '08 sport its a nice unit, kind of spendy though. As for the tail light guards Westin used to make 'em but they don't make them any longer. I got some from AriesAutomotive
looks like they make a grille guard for rangers also it looks pretty similar to the Westin one I know the aries tail light guards are almost a direct knock off (they mount differently). I think the tail light guards look good but the finish on them is a little soft and the welds do not go all the way around the small bars, other than that they are pretty cool.
