No and no. An aura would have to grant Haste in order to overwrite summoning sickness. The two effects of Furor of the Bitten and Bloodcrazed Goblin do interact though. The resulting creature would be a 4/4 that can only attack, and HAS to attack, if your opponent has been dealt damage this turn.

The key is the phrase "if able." If a creature has a restriction that makes it unable to attack, then it won't be forced to.

Generally in Magic "can't" effects always take precedence over "have to" effects anyway, but must-attack effects always have that "if able" clause for this reason.
