Okay, first of all, a certain amount of fire resistance is innate to Divine Ranks of 0 or above...but that doesn't mean that everything we face has to have divine ranks. So that's one thing to keep in mind. D&D has a lot of different templates that can make normal monsters into epic monsters.
The interaction between Cold Subtype and Fire Resistance is as follows:
You subtract the Fire Resistance from incoming fire damage, then double what's left.
Thus, a Scorching Ray would have each ray reduced by 20, then whatever got through that would be doubled.
Damage Resistance (as distinct from energy resistance and spell resistance) only operates against -physical- damage. That 35/+4 will operate against weapons, falling, collision, etc...but even a lowly magic missile spell will penetrate it automatically.
Also, Hellyasillel's bow is +4 if I'm not mistaken, so it pierces the 35/+4 damage resistance. This means the only DR that's applicable against the bow is the much, much lower DR4/-. That would be applied per arrow, of course.
As for being a fire deity...Scorching Ray is a terrible spell to use against things with resistance. This is because it's several small attacks, each of which is resisted seperately. If you want to punch through resistance, you need to use a single larger attack. This is where your Fire Seed (10d6 ranged touch, no save), and similar spells come in handy.
Fire Resistance 20 is really no big deal if you have some decent high level fire magic at your disposal...which you do.
