High Mileage Grand Prix Expected Problems

So I have a '04 NA GP with 161k on it and its had a number of issues with it, mileage related and I just want to get an idea of what I might expect in the near future what I could expect to go wrong, here's a list of whats been done

coolant elbows, LIM gasket, water pump, alternator, thermostat, rad flush, coolant sensor, belt, plugs & wires, rear caliper (ebrake BF leak), crank sensor

I'm due to swap out one of the transmission lines which is leaking and I have a rear hub I need to change as well, bad abs/trac sensor

My main question is what else should I be on the lookout for or expect to go bad as I want to keep it around for awhile...

injectos, MAF, TPS, idle control valve, HG, what should i be worried about lol, thanks
 


you already got the coolant elbows and LIM gaskets changed which tends to leak after a while. might be a good idea to change the valve cover gaskets as well as they tend to crack and leak. since you're planning on changing one of the trans lines might as well drop the pan and change the pan gasket and add in new fluid for what was drained fro the pan. this is not to be confused with a trans flush! HG on these cars tend to last a long while. my motor's an L67 though but gets runned hard and it has over 200k plus miles.
can also check the lower motor mount and trans mount as well as the control arms and ball joints for any play.
