One thing about pruning roses.
You could get 50 expert rose growers from around the country together
and you would get 50 different lots of advice about when to prune.
It depends so much on your local weather/climate.
you can get more than 3 months difference in pruning times.
It's often best to leave it till early spring so that a mild spell after
pruning doesn't get the buds bursting and then getting damaged by late
frosts.
Some people will say to always leave enough stem below the cuts so that
if you do loose new shoots there are still dormant buds to follow on.
Also if you are pruning climbing roses then if you can bend the stems
down you will get more flower growth (The same is true of fruit trees,
if you can bring the branches down so that the sap is trying to flow
down hill then you get more fruit buds}
