You shouldn't need a crank puller for a megaexo crankset.

The Park Tool site has pretty comprehensive instructions on installing and removing various cranksets here:

These are nice BBs. They have good sealed bearings in them and the hold up pretty well too. Take care of them though, don't just hose your bike off after a muddy ride and let it sit. Take the time to pull your cranks off (its really easy with this type of FSA crank) and clean things right and keep everything lubed. If you do this is will give you lots of good riding. If you abuse it and let water sit in there you will destroy it.

So you also pull you bb out and individually dry the sealed cartridge bearings? Cleaning and maintaining your bike is important, but there's not really much you can do for a sealed bb other than try not to submerge it and let dirt eat away at it. Pulling your cranks off every time you clean your bike is a little excessive imo. I haven't been too impressed with FSA's recent bb lasted less than 6 months while being properly maintained & cleaned.
