Is my rear cassette worn?

I've just replaced my chain as the previous one was worn (was measuring showing about 10 1/8). I also took the opportunity to strip the cassette and jockey wheels.

With the new chain on I've noticed a clicking noise - a bit like the noise you get when bearings have gone on the bottom bracket.

On closer inspection it looks like some of the chain links are catching on one of teeth. This happens in any gear and appears to be at the teeth that are located where there are grooves in the individual sprockets (I assume these grooves are to help gear changes). The teeth look bent to me?

I've taken a couple of pics to show what is happening.

I did also notice a bit of sideways movement in the cassette, however I'm pretty sure that was there before?

Any ideas?

Are you sure the chain is the correct speed, i.e. 9 speed & not 8. It looks like it's too wide.

The grooves in the sides of the sprokets are there to assist gear changes.
