I never take the cap off-- it should have a vent hole in it-it has to (otherwise it would not feed properly) so most likely, the fluid has pushed its way out the vent an drooled down by where you see it- should be no big deal- I assume the reservoir is full- a good indicator that it ran over.

All brake pedals will go to the floor after pad change- you need to slowly "pump them up" to get the pistons in the right spot- it may take several pumps- I never pump at full stroke though, I don't wish to put that master cylinder plunger in a place that it hasn't been before- due to posible corrosion that may tear out an o-ring or other seal. Heck, i know mechanics who put a 2x4 under brake pedal to avoid full stroking the master cylinder when replacing pads.
