It's usually outside in a hanging basket, but just brought it in as we're expecting some bad weather--Tampa Bay Area. If so, where should I cut at, and is this fall a good time to pot it or should I wait until spring?

Don't cut it!!!!
Those small plantlets are called keikies, which means baby. Once it has several roots between 2-3" long, it can be removed from the mother plant.
Just use the back edge of a butter knife as a wedge between the bigger cane and the baby. With just the right pressure, it should pop right off.
It is from a Dendrobium phalaenopsis orchid. You can pot it up using the proper sized pot and the appropriate media. Quite probably a three inch clay pot would work nicely.

Would this be a good place to pop it off?






I just noticed that the encircled joint at the end of that cane feels like it would pop off; if so should I use the whole cane or pop it off closer to the keiki?









Every year I have to rotate the basket as the W facing side grows out real long towards the sun; this cane with the keiki was last years long growth, had nice dual flower spikes.





In the background is the one with the keiki, is after I rotated it to the back (those in front are blooming right now :)

(I didn't notice the keiki until now because as you can see it was out of sight behind the tree branch. Have had this orchid for over 10yrs, it stays out all winter, is very hardy.)

The best place is right where the baby plant is attached to the mother plant. If you do it, no cutting is involved. There is no reason to cut. If you cut, you are creating a possible source of disease or a rot to enter and possibly kill the plant. Why do that.
Trust me, the butter knife works very well.
Almost every root should go with the baby plant.

Does this orchid bloom every year for you?

I can feel that, it will pop right off at the base of that cane; and yes it is a prolific bloomer

Then I assume that it will do just fine going forward.

Yup, have had it for over 10yrs now, first keiki though; think I can just plant it in with the mother plant or does it need it's own basket?

Yes, you could do that but you are risking water and root damage. The mature plant likes such and such. The baby likes similar overall care but not the same watering schedule.

Ideally so, but these cane orchids are pretty hardy down here in FL (9b.) I had the mother plant in a 6" pot before transplanting it to the current 12" basket so it was easy to find a large unused section of the basket with none of the mother roots and I planted the keiki there along with the entire length of cane.
