Welcome aboard! Always nice to see another VR6 around these parts, pretty soon we will have all of them
Edit your profile and let us know what state your in, maybe a local come drop by and have a look with you.
As for taking on a risk. With a VR6 there are a range of commonly broken parts... like power windows, heater core, AC... the list goes on a little. But at $3,500 there is plenty of cash on what a good one would cost anyway.
Coolant leak is probably the crack pipe, the auxillary pump or the water pump, all relatively cheap to replace.
Oil leak... could be lots of things, gaskets aren't exactly expensive either, but you would want to check where it's leaking from.
Engine mounts are also relatively cheap.
Stop light... should be just a bulb.
What year?
How many km's? (timing chains done?)
What are the seat bolsters like?
um... I'm sure the cavalry will be here soon to offer more advice.
