A halfling Paladin 2/Monk 3 has obscenely good saves: 5,3,3 base +1,1,1 for race + Divine grace + ability mods. Concentrate on Wis, & Cha, take the Zen Archery feat to use your Wis mod, rather than Dex on ranged attacks. IMC, we like to call this class combo "immune to harm."
A Fighter with just 13 Dex can take Whirlwind Attack at 4th level. Make him a Human with high Dex and you'll get the bonus feat that you can spend on Weapon Finesse (Spiked Chain). When he's completely surrounded by medium-sized foes two squares deep, he can attack all 24 of them in one round at his highest attack bonus.
A Sorcerer 1/Ranger 4 has decent saves (4,4,3 base) and can cast true strike twice per day. An archer, and if she's an elf, a candidate for arcane archer. This character also has decent skills, an animal companion to help defend her and a familiar to help spot foes.
