Well, for character generation, I like to do 32 point buy. Hit points are max at first level, and then 75% thereafter (+ Con of course). Genasi are available as a potential race, in addition to the normal PHB races of course. I would like good or neutral characters, no evil please.
Here are the different genasi that exist in Low'verok...
Ok, here's a quick run-down of all the various types of genasi, their powers, where they come from, and general personality. I'm going to list the four basic elements first, then the para-elements, and finally the quasi-elements. Note that all genasi have darkvision 60', so I won't bother including that. This is only the quick and dirty version, so if you end up deciding to be a genasi I can clarify things for you. All have a +1 ECL.
Four basic elements
Air - Air genasi are touched by the Elemental Plane of Air. While they are quick of hand and sharp of wit, they can be easily distracted, and proud of their planar heritage to the point of arrogance. +2 Dex, +2 Int, -2 Wis, -2 Cha. They can levitate once per day, as per the spell. +1 racial bonus vs. air effects, which scales with level. They do not breathe, and thus cannot suffocate or drown. Electricity resistance 5.
Earth - Earth genasi are touched by the Elemental Plane of Earth. They are strong and tough, but somewhat oblivious and stubborn. +2 Str, +2 Con, -2 Wis, -2 Cha.

Acid resistance 5.

Fire resistance 5.

Negatai - Negatia are quasi-genasi touched by the Plane of Negative energy (the energy that powers undead). The nature of negative energy imbues them with a certain amount of strength, but also makes them more susceptible to death. +2 Str, -2 Con. +1 racial bonus vs necromantic spells and effects, which scales with level. -2 racial penalty to all saving throws. Unintelligent undead will ignore a Negatai and won't attack them unless they attack first. A Negatai can rebuke undead as a cleric four levels lower than his current character level, or if the character already has the ability to rebuke undead, he may do so as if he were two levels higher. They also no not heal as fast as other races, with natural healing being slower and healing spells being less effective on them. They may cast chill touch 1/day, as per the spell.
Positai- Positai are quasi-genasi touched by the Plane of Positive Energy (the energy that powers healing spells). They are filled with positive energy, which improves their health. However, their energetic state makes them somewhat hyperactive, with a short attention span. +2 Con, -2 Wis. +1 racial bonus vs necromantic spells and effects, which scales with level. -4 penalty to Fortitude saves made to recover a level drained by undead, and undead do more damage to Positai. They may turn undead as if they were a cleric four levels lower than their character level, or if the character already has the ability to turn undead, he may turn them as if he were two levels higher. Positai heal at a faster rate than other characters. They may cast cure light wounds 1/day as per the spell.
