What shall I use to polish the woodwork on the speakers?
And what is the best way to connect the speakers to the amp.?
I,ve put the R and L to the A terminal and the sub to the B terminal.

This was used as on the walnut finishes by JBL: 3/4 boiled linseed cut with 1/4 gum turpentine.

I've personally only used boiled linseed to protect and feed my finish.

Your speaker connection looks fine. The sub was designed to connect in parallel to the main speakers.

On every amp. that I've seen with A/B terminals, they connect in parallel internally.

The Ultrabass has an extremely high impedance and is intended to be run in parallel with the satellites. You can use the connections on the Ultrabass to feed the satellites, or run them separately from the amp. No need to consider using A-B connections, just use the one.
