the best thing to know about the IC'ers is practise, practise, practise... when i first picked the IC'ers up as my main. i spent 3-5 hours everyday practiseing chaingrabs and dysnch's and i still do, the first thing is to learn the basic's of the ice climbers, your basic chain grabs and dysnchs like dash dysnch, or an easy one to pick up is the f-smash dynsch just tap one direction and then when u tap the other diraction fast hold it and press attack as if u where charging a f-smash popo will charge nana will stay still allowing you to IB blizzard w/e u want, after that learn dash dysnch into IB and blizzard, then work on jumping dysnch'ed blizzards from there let your imagination do the work and throw in other stuff like blizzard to u-air to n-air to blizzard stuff like that.... but its all practise and learning the match-ups and zoning. hope that helps, also i have been playing IC'ers for almost a year now, and i do quiet well placing first/second in almost all the tournys i attend in BC/vancouver island, and i still practise CG's and dysnchs everyday... GL my friend i hope you enjoy this awsome and fun character to play.
