IMNSHO, a Tiny race with -8 Str and +8 Dex and no HD would be ECL +2. Spellcasters still don't enter melee, so the -8 Str means little; Tiny and +8 Dex combine to give the creature +6 AC! Of the core races, the spread is -1 AC to +2 AC; there's nothing this extreme.
In fact, compare this race to elves for wizards. Elves usually make decent wizards (it's their favored class, after all), but have only +1 AC and actually lose hit points from their Con penalty. This race would be tougher...
I suggest a -2 Con and -4 Cha (look at animals' Charisma in the MM). This should be enough to make the race ECL +1 at least.
