Advice on Blooming plant

I am new and made a mistake by posting this on the wrong board. I got the site right but the board wrong .
I looked around and found this one. I hope this is the right one!

I have a very nice, outdoor potted plant that is appx 2.5' and blooming nicely it seems.
It won't produce a lot, but the quality is outstanding. The leaves even pack a little punch.
I've always had a green thumb but I'm new to this.
Right now, it has appx 12-14 tops or flowers. The larger tops are about 1 month old. They have continuous white hairs (best way to describe them) on them as they begin growing (from the time it was a tiny plant these "hairs" appeared) and throughout the growing process. I see a touch of purple in the flowers because some of the leaf stems are, I assume.
Anyway, I am at a loss as what is best for optimal results at this last phase of growth. It came from a tiny white seed I was lucky to find and when it did manage to sprout, it took patience, attention and some hormones to give it a strong base to even grow. It's a runt, but I'm proud of my little girl! Here are my questions I would be very grateful to have any answers given to:
Should I be feeding it anything?
Do all the leaves (some large in proportion to the plant now) need to remain on the plant-- including the ones near or coming out of the flowers?
I have no idea what the time frame should be. It has some new flowering going on and the larger ones are getting bigger.
Do I just let it go until frost arrives in about 2 months?
I have people bugging me to death asking for clones.
I have no idea if it would work with the rooting powder and hate to remove more than a leaf. It could harm it, in my opinion.
Again, any advice or contacts to other sites (I've read a lot of info) would be appreciated very much! Thanks in advance!
