In SM you really shouldn't ice block, hopefully you have frost nova and can use that to escape, blink. I also have some points in magic absorption, so every time you resist the low level spells you get back quite a bit of mana. Try to use LOS as well to get as many mobs together as possible.
Also for Cath, I always do the last boss. Once you clear the front area of the Cath itself, once you engage the boss, the mobs from the left and right will come to defend him, and it saves you the time of rounding them up to aoe.
