Techno's Wolf strategy:
0%, hop around and spot for a grab, combo F-throw, u-air, f-smash, and then go for a gimp with D-airs. If this works then sweet, if not then he's at 40% or so and will be more careful about getting grabbed. From there jump over stuff and pressure with d-air and b-air, and try not to stand still, and eventually kill with f-smash. None of this is guaranteed of course, but it seems to work pretty **** well. I also go for a lot of grabs and get my grab hits in to reset my diminishing returns and put Wolf in the air.
After that it's all just a matter of dealing with common Wolf problems, like his smashes and his dodge->jab, and his lasers. If you find yourself getting spot-dodged a lot, use your dash attack more often. If the Wolf tends to throw out more than one smash in a row, after the first smash, simply d-air him, and you should beat the second smash. If there are a lot of lasers flying around, just jump over them and d-air his face.
I'd say 65-35 Kirby.

Sheik:
Needles can be a pain, as can the f-tilt. Sheik really needs a better way to get around your B-air spam though to be really viable against Kirby. 70-30 as well.
Zelda:
WTF Zelda is what I usually think when I play against her. She kills you at low percents and has a lot of meaty priority, so you basically have to mindgame her into doing things that you can beat out. I like to do the same as I do against Wolf, go for grabs to build damage and get her in the air so I can mindgame her landing.
For the record, however, her downsmash ***** your recovery, so try to grab on with jumps where you can.
