Yes. If I understand what you are saying you will be slipping the clutch, which will wear the clutch out really fast.

You slip the clutch when you need to, to get yourself going up a steep hill. The clutch will wear but it will provide a reasonable life if you are reasonable about slipping the clutch.

Slipping the clutch to keep the plugs from fouling would be just plain foolish.

What's the problem with shifting down?

are you talking about constantly riding around half clutched all the time? If so your clutch wont last long..........at all. It would be like driving around with the brakes on all the time, as far as clutch wear.

You should know your bike enough to the point where to shift. If it feels like it has no power and your just reving the piss out of it then shift but just because your at a higher RPM dosent mean your bike will blow up.

The black stuff is "spooge" and is a sure sighn of a bike that is not jetted properly. The little CR's don' have the greatest seal system where the expansion chamber meets the cylinder so some is pretty typical but avoidable if properly jetted. Properly jetting your bike will fix your power delivery issues as well saving your clutch assy. some wear and tear. Bottom line is a fresh plug, properly jetted carb, good fuel & oil mixture and properly adjusted a lubed cables seem like they will have to riding a bike that feels vastly different. Selling this bike won't fix it when stuff starts to wear or need adjusted on the next one.

Do a search for jetting here on DRN. Lots of good threads concerning jetting here.

You do have a manual for your bike, right?
