Yep, that's it. When you are at full extension on the driver side, it will rub. Keep in mind that you also lowered the transfer case (which lowers the driveshaft, further reducing clearance). If you had a bigger lift, it would limit extension of that wheel.
I cut mine at the edge of the skid (where the red arrow is) so the crossmember only attaches on the passenger side. That skid still attaches to the TX case skid and seems to provide enough protection. I've bounced it off multiple rocks and my transmission pan is still untouched, so I assume that the skid and shortened crossmember don't flex much.
The noise is just something you'll have to get accustomed to. Keep in mind that all the noises are exaggerated inside the vehicle. Kinda like a guitar, the body acts like a sound box and amplifies the noise. Once again, it's all just part of the game.
