There's a high degree of overlap between the Tolkien hobbit characteristics you enumerated, and the 3e rules for halflings.
I ignored the illustrations and the fluff in 3e, and assumed halfling = hobbit. The rules work VERY well for that.
Let's compare 3e rules v. Tolkien characteristics, shall we?
3e characteristics of a halfling:
•+2 Dexterity, -2 Strength.
•Small: As a Small creature, a halfling gains a +1 size bonus to Armor Class, a +1 size bonus on attack rolls, and a +4 size bonus on Hide checks, but she uses smaller weapons than humans use, and her lifting and carrying limits are three-quarters of those of a Medium character.
•Halfling base land speed is 20 feet.
•+2 racial bonus on Climb, Jump, Listen, and Move Silently checks.
•+1 racial bonus on all saving throws.
•+2 morale bonus on saving throws against fear: This bonus stacks with the halfling’s +1 bonus on saving throws in general.
•+1 racial bonus on attack rolls with thrown weapons and slings.
•Automatic Languages: Common and Halfling. Bonus Languages: Dwarven, Elven, Gnome, Goblin, and Orc.
•Favored Class: Rogue. A multiclass halfling’s rogue class does not count when determining whether she takes an experience point penalty for multiclassing.
