Philadelphus is pruned after flowering. Simply remove all flowered shoots and the odd oldest branch to ground level. Your one year old will need pruning only when it has flowered.
Roses? Don't grow them now but essentially remove all flowered stems to buds lower down. There is a difference between climbers and ramblers, etc., but basically pruning is done in autumn and then in spring.
Have fun with pruning. See how things flower ... For example do flowers appear on ends of new branches or on old ones?.....and use a little logic or read up on them.
