Not suckers. Normal new growth, if a little damaged poss by aphids. Not a problem tho.
Has it had any rose fertiliser this year? If not I'd give it half a dose. It's still a baby getting it's roots established.
Prune it hard back to about 9" from the ground, pruning to an outward facing bud. It'll soon build up a good framework of stems.
