For motor mounts I would get either Mopar Performance or Polybushings.com The MP are higher durometer rubber and are stiffer than stock. The PB.com are polyurethane. I have had MP mounts in my Omni and Lancer for several years now and they have held up great. I have PB.com motor mounts for my Spirit R/T, although I haven't installed them yet. You'll likely find that OEM mounts are a lot more expensive than MP or PB.com. Don't go with aftermarket parts store mounts; they suck.
If your stock rubber brake lines are deteriorating, I would replace them with the SS braided ones that FWDP carries. Check to make sure they aren't splitting on the outside or swollen. A bad hose can cause brake failure or a sticking/dragging caliper.
I bought a set of the SS braided brake lines from FWDP for my Omni, although I haven't installed them yet. My stock brake lines looked OK, but I have the front and rear sub-frames removed from the vehicle so now will be the easiest time to replace them.
