Your plant is a Crassula ovata var. 'Skinny Fingers' or whatever they are calling them these days...

This looks like a bug problem. This is not my forte, so I will let others handle it.

In terms of tips, this plant looks a bit light deprived. It will want as much sun as you can give it, and then reward you with some nice color. Keep it outside if/when possible. Remember, if you move it into really bright light all at once, it will burn. Make the transition slowly.

Ahhh it's mealy bugs! The bane of my existence. Get rid of these asap they can wipe your plant out in no time. Get some rubbing alcohol and q-tips. Dip the q-tip in the alcohol and remove the pests. Check the plant thoroughly. Check other plants if you have them.

oh all right! will do! thank you both for your help!
