No, I don't think that's a sucker so no need to worry about it.
It looks as if your rose is quite happy and the healthy new shoots are growing well.
I would give it some specialist rose food (according to the instructions on the pack ... don't overdose)
and next Jan/February I'd take it out of the pot and remove the loose compost and re-pot it in John Innes No 3 loam-based compost.
When you repot it I would bury the graft point (where all the stems are coming from) a good 2 to 3 inches below the surface of the soil.
It looks as if it's going to grow quite a few new long shoots so next year it may be better to find a bigger container for it. If so, try not to get one that curves in at the top ... it'll make it easier to look after and as you say, ensure good air flow at the base.
Yes, I'd fill the pot much nearer to the top of the pot ... leave about an inch and make sure that there are plenty of drainage holes in the base of the pot so that it doesn't get waterlogged.
In the winter it's a good idea to stand the pot up on pot feet or three half bricks to make sure that the drainage hole can't get blocked.
A few yellow/black leaves are not unusual on some roses ... pick them off and burn them so any fungal spores don't spread.
Otherwise that looks like a lovely healthy rose bush
Do you know the name of the rose? That would help with pruning decisions.
