IO slotting question

[Dragonfire]

I'm planning my claw/regen scrapper, and looking through the IOs available I have a question: do I need to slot an entire set onto one power to get the bonus, or can I put them on any series of powers and get the set bonus?  Preventative Medicine, for example, if you have 3, gives you 25.1 HP bonus.  Do I need all 3 on my fast healing, or can I spread that out onto various healing powers?  Thanks!

For set bonuses they all have to be in the same power.

I suggest checking out the Scrapper forums, there are likely some builds floating around there you can use for ideas. Also Scrapper forums are generally the most helpful and always the best.
