I don't think you can use a swift action and free action in the same round? And I don't think you can turn a spell into a swift action with a quicken feat?
A free action is an action that can be used as many times in around as the DM sees fits. For example talking is a free action so you can use a free action in any round no matter what you have already done as long as the DM is ok with it.
A swift action can only be used once per round and it is usually an action that results from a feat or an prestige ability.
Here are the definition of swift and free action from the SRD:
Free Action
Free actions consume a very small amount of time and effort. You can perform one or more free actions while taking another action normally. However, there are reasonable limits on what you can really do for free.
Swift Action
A swift action consumes a very small amount of time, but represents a larger expenditure of effort and energy than a free action. You can perform only a single swift action per turn.
Once 3.5 came and swift action were introduced a quicken spell became a swift action. Here is the definition of quicken spell from the SRD.
Casting a quickened spell is an swift action. You can perform another action, even casting another spell, in the same round as you cast a quickened spell. You may cast only one quickened spell per round. A spell whose casting time is more than 1 full round action cannot be quickened. A quickened spell uses up a spell slot four levels higher than the spell’s actual level. Casting a quickened spell doesn’t provoke an attack of opportunity.
Special
This feat can’t be applied to any spell cast spontaneously (including sorcerer spells, bard spells, and cleric or druid spells cast spontaneously), since applying a metamagic feat to a spontaneously cast spell automatically increases the casting time to a full-round action.
