Lots of people on here who know much more than me on roses. But it looks like a good specimen to me! You can see all the new and healthy growth.
You're probably a bit too late to prune it now....theoretically it should have been pruned at the beginning of the month. You may just be able to get away with it if you want too though.
If it were me, i would prune it, and plant it out.. somewhere with good amount of sun! Dig a big hole, fill it with compost, some grit and growmore (fertilizer).. water it well then stick it in. Keep it watered, but not drenched.
The plant does look quite congested, so when you prune take off all the dead branches first, then the branches which are cross over each other and rubbing against each other. Then you can take a third off each the whole thing. You essentially looking for an open expanse in the bush which allows some airflow.. Dont worry, you can't really over-prune roses as they'll bounce right back!!
I'll let others chime in who know 100x more than me now...
