Oh, I thought my three actions were: move, whip attack, hammer attack. But I'll take another whip attack to trip the third goblin if that's allowed.
Or would I be able to make another set of two attacks? would there be more than my standard dual wield penalties for the second round of attacks?
You could make an additional attack with one of the weapons. Improved Two-Weapon Fighting will allow you second action to be made with both weapons. You will suffer the standard -5 to attack rolls for making an additional attack.
You could also make that whip attack to attempt to trip if you want (Also with the -5 penalty)

When you fight with a second weapon in your off hand or with a double weapon, you can make two attacks with the first attack simple action you take during your turn: one with your primary hand and another with your off hand. You take penalties on these attack rolls as listed on Table: Two-Weapon Fighting Penalties. Any other attack simple actions you take during your turn allow only one attack roll, using either the weapon in your primary hand or the one in your off hand.
If you have the Improved Two-Weapon Fighting feat, you can make two attack rolls on both the first and second attack simple actions taken during your turn; both of the attacks made on the second attack action are made at a –5 penalty. Further attack simple actions taken during the same turn allow only one attack roll, using either the weapon in your primary hand or the one in your off hand.
If you have the Greater Two-Weapon Fighting feat, you can make two attacks on each of your attack simple actions on your turn, though you take all the normal penalties for two-weapon fighting, as well as the cumulative –5 penalty per attack simple action (all attacks made as part of the same attack action have the same penalty).
