$880 is a bit much, but would take care of the issue..until that Penn salt gets to it again. ;0) Perhaps a spot weld IF they can find the leak in an accessible location would work for you. I have had that done on a '01 Quest van (VG33) manifold and I believe it lasted a few years.
Cleaning the injectors and throttlebody -- I've paid similar to $150~ to have that done at the dealer, spread out over the 100,000 miles I had my coupe. But I would NOT cheap out on that for too long. Build up on the injectors is bad news down the line. Build up on the TB can also start to cause rough engine idle etc. on certain cars more so than others. I had a 3.5, not 2.5, but I imagine you really want to get maintenance items done first before throwing away play money you don't sound like you really have (no offense).
Perhaps you can try to clean the TB yourself if you're good at that stuff. I did that on another car just the other day, and there was a layer of black dirt caked on directly on the throttle plate itself and the piping and immediate internal area of the intake manifold. Of course this other car has 250k miles. As for the injectors, you can probably get away with it for some time not doing the service, or maybe running a bottle of Fuel Injector cleaner like Gum out ($4-5), or whatever reputable brands you can google up, wouldn't hurt every year or so.
