Please help me melt my PCs

A community of Salamanders could also be fun, especially since you get to give them class levels then
Swordsage Salamanders with Desert Wind and Shadow Hand, teleporting snakes that burn, and then burn a little more.
Team it up with a dispelling caster.

Well, a quick search of the srd for monster with the fire subtype yielded:
- Azer
- Brass Dragon
- Fire Elemental
- Efreeti Genie
- Fire Giant
- Gold Dragon
- Hell Hound
- Magmin
- Fire/Magma/Steam Mephits
- Pyrohydra
- Rast
- Red Dragon
- Salamander
- Thoqqua
A search for the earth subtype yielded:
- Blue Dragon
- Copper Dragon
- Earth Elemental
- Gargoyle
- Stone Giant
- Earth/Salt Mephits
- Xorn

Don't forget that water/cold themed enemies could be attempting to make some kind of an assault on the dungeon. Make for some three way fighting, or maybe a neutral third party.

Obsidian Oozes are downright mean. Oozes only get +1 CR per +4 HD and fractions round down, but a size increase would be +1 CR. I'd stat them out at 18 HD Huge (CR 11), 16 HD Large (CR 10), and as-printed (CR 9), and use three to five per encounter for seven PCs but never more than one huge ooze per group. I think the 'Skewer' special attack on its stat block should actually be changed to 'Sharp Spines' based on its ability descriptions. These things will completely destroy anything that's not outright immune to fire.

some half dragon monsterous spiders who spin webs of pure magma!

Well just a bunch of half-dragons of various creatures, and kobolds who make lava traps all over the place. Mabey even a hatchling or two.

That doesn't seem fair when you're obviously going into a fire dungeon.

I disagree. If I have an obvious energy that will be prevalent around me (fire) and one of my main attacks is the same kind, I expect someone coming after me is going to be prepared for it. So I will prepare alternatives so that a simple immunity to fire won't negate most of my abilities/defenses.

Doing otherwise for an intelligent foe just makes it less believable.

Don't forget to make your Living Spells Searing.

Have them fight an iron golem in a room full of glyphs of warding tied to fireball spells. For added lols, throw in some red dragon shamans or some spellcasters throwing fire spells.

Living Spells tend to be extremely weak relative to their CR. If you use more than one spell it's almost guaranteed to never hit a character who doesn't completely dump AC.

I'd put a few permanent Wall of Dispel Magic or (Greater) Dispelling Screen effects in choice locations. A smart dragon would want to remove any intruders' spell protections prior to engaging them.

If you're going to use an Iron Golem, be sure to put multiple Wall of Fire + Permanency effects in its room. A 20 ft. wide hallway with Wall of Fire cast against both walls would give it within-ten-feet of both spells if it's in the middle of the hallway.

Half-Dragon has been mentioned a few times, but don't forget about Half-Elemental in Manual of the Planes. Half-Dragon Trolls and Half-Elemental Nagas would be pretty brutal. Half-Dragon Blackscale Lizardfolk (MM3) Barbarians and Half-Elemental Gauth Beholders (advanced) would be interesting.

Make sure that you form a proper believable ecosystem as well. Nothing ruins immersion like the realization that all creatures in a particular biome are physically incapable of doing harm to one another.

Living Spells tend to be extremely weak relative to their CR. If you use more than one spell it's almost guaranteed to never hit a character who doesn't completely dump AC.

So adjust their CR. It's not like you have to follow the recommended guidelines. Sometimes, if you do, it's a bad thing. Just depends on the party, their abilities, and the specific monster and the specific environment.

Living Fireballs are still cool.

Right! Wall of Fire! That spell was right at the edge of my thoughts the whole time.

Ooooh just flicked through the MM5 and saw the Magmacore Golem. Its just so damn awesome. Well worth looking into

A tribe of Fire gnomes (planar handbook!) who worship fire elementals.
Some with a small fire elemental familiar.

And well they are gnomes, let them do all kinds of crazy stuff, like cheering if they are used as footballs by a fire elemental
