For both thieves and bards, I highly recommend playing hurthlings or gnomes. Reason is that these races get a free starting talent. If you also roll Candle, then you are guaranteed 3 talents (4 for bard, in fact). Take Charming, Boon to Family, and Heir. This will give you an excellent item--in the case of bards, the awesome seven league boots (double your movement speed with no downside); in the case of thieves, a very nice penetrating dagger. 3 talents might seem a waste for one item, but it's (IMHO) very worthwhile for these two classes.
Hoping to win with every class, doomed. Archer, Barbarian, Bard, Beastfighter, Druid, Elementalist, Farmer, Fighter, Monk, and ULE Priest down.
