For 1), I strongly recommend the BOBOVR M2 strap. My face was hurting after using the original strap for an hour. The Elite strap was better but the BOBOVR is the best: no more pressure on face.

I purchased both the M2 and F2 on aliexpress (2-weeks of delivery but much cheaper).
I even got the BOBOVR F2 (fan) to avoid lens fog (it happens after hours of exercising within the VR world).
