Flicking off the sand...

You can change the floss on your HOB but leave the 2217 alone. It will be fine. As far as the flashing on the sand occasionally, more than likely it is just an itch from getting use to the "new water". The vibrating is either them deciding the pecking order or "Hey baby, do ya wanna". Congrats on the new fish!

Nice! I'm still keeping a close eye on them though, slightly injured fish, flicking and what appears to be, more agression.

Pics tonight! (Sorry i didnt have time the other night)
 
Yeah, change your media out, and the next water change, siphon out some of the cleaner water in the column, and rinse the Eheim's media. Do this every water change, or once a week. You should change your pads once a month or as needed, just change one at a time, your bacteria colonies should be fine.
As for your injured fish, he may need to be quarantined until he recovers. I'm sorry I don't know the tank size we're talking about. 55? With 9 Mbuna? Is that correct? If so, you may need to add a few fish, or remove males and replace with females.
 
flashing is perfectly normal if they do it here and there, when it becomes an issue is when they do it and dont stop if they have ich they will flash pretty much all the time til you can cure them, if the rusty has ripped fins than you have a fish that is picking on it and poss by its own kind.

55 Gallon - Eheim 2217 + HOB

7 Yellow Labs (2-2.5 inch)
6 Aceis (2-2.5 inch)
6 Rusties (1 - 1.5 inch)
1 RTBS

The little rusty (1 inch) is hiding in a place the other fish cant reach, he seems to be fine, the torn fins aren't that bad, just bad enough to make him go into hiding.

They don't flick as much anymore so thats good. I've noticed some ditches in my tank, whoever the hell made them lol.

Pics asap!
 
Well, your stocklist sounds fine, you might just need to swap males for females down the road.
I agree with Jpappy's filter pad advice, mine are always falling apart after a month, so I usually change them a bit early so I can plan on alternating ahead of time. Otherwise, I've had to keep a filthy pad for an extra week just so I'm not changing both out at the same time. Probably wouldn't hurt so much depending on the amount of rock structure in the tank, but I get paranoid all the same.
 
Your fish could also be just trying to stir up any left overs that might have fallen to the bottom.
