All of these (Choke, RFC, L) are basically just coils. There is no
positive or negative, there is no polarisation, they can be installed
either way 'round and it shouldn't make any difference which way 'round
you install them.

I installed all of mine in the same orientation as resistors (which are
again unpolarised) - so the bands can be read left-to-right, or
top-to-bottom.

Yes, the extra band (usually gold) is a tolerance, again exactly like
the resistors.
