Ok, now I see what you meant about the triangle image! I'd forgotten that I'd even loaded an image here in the gallery.
There are a couple more pics now, one from the side and one head on.
Thanks for the comments, all. I finally just went ahead and ordered most of what I could see being accessible while the engine was on an engine stand, and would be a pain when it was reinstalled.
Timing chain, tensioner, and all guides(may not get to a few of them, but ~$20 for all the lower ones, couldn't hurt)
oil pump chain/guide
valve stem seals
intake/exhaust gaskets
intake manifold plenum seals
cam oiler clips
valve cover seals/crush washers
rad hoses
water pump gaskets
thermostat/seals
engine/trans mounts
flex discs
front/rear main seals
Hopefully all this will give a bit of a headstart on keeping this engine running in good shape for the foreseeable future! (especially since it hit me what I just dropped in preventative maintenance parts.. My bank account is hating this car already, and I haven't even driven it yet!
)
