It will fit that shim if it doesn't already have its own. Is it better than Claris? It's prettier and lighter, but I've used both with Silver shifters and they were great..I suspect you have a problem elsewhere causing unsmooth shifting. Or it's a worn out Claris.
I don't remember if I shifted a triple with CX70 so can't help there, but its narrowness might be an issue with an 8-speed chain. It means lots of trimming to keep those cage plates away from the chain, a thing I'm very OCD about and don't enjoy at all. If you're like me, stick with 8-speed front derailers!
