How exciting! And this does sound more promising, more like a love at first sight, which should be much easier. It's really the only kind of bonds I care to do anymore as I don't like dealing with the stress of the other ones.
So her color is black otter. Rex fur is the softest bunny fur there is. It's like velvet, so yes, you pretty much just want to sit there and pet them all day.
So with doing the fast method of bonding, if they truly are love at first sight, it kind of just happens naturally as they want to be together so much that it makes it fairly easy. I would do a test run first and put them together in the bathroom or other small area for several hours if possible, and just observe how they react to one another. If they instantly are getting along then I would set up an area that you will be able to keep them in 24/7, where you will be able to monitor them and keep a close eye on things. Your bedroom could work if you can make an area neutral. Though I will say that with my love at first sight bond, I ended up just putting them in the does permanent area right away without neutralizing anything, as they got on so well and desperately wanted to be together. But if she does still seem too hormonal and wants to hump him too much, then hold off the bonding and give her a few weeks for the hormones to fade.
You can't really rush things too much if they really like each other and you are seeing signs they really want to be together. In fact delaying things too long can actually cause problems because the tension can build and cause issues. It's a balance of determining what will work best for their personalities, and sometimes it's difficult to tell when you don't have a lot of experience with rabbit behavior or bonding. You just have to forge ahead sometimes and hope it's the right choice. If you go with the fast method and it doesn't seem to be working out, you can always backtrack and take it slower if you need to.
With the pellets, since she likes hay, free feed that and just gradually start increasing her pellet amount each day til you get to the normal amount you want to feed her. Unless you are able to get them bonded, then you may need to accelerate her pellet amount some, as you will then need to feed them together.
Bugs wound will heal as long as it doesn't get infected. If it did need stitches you would see a significant depression or indent where the wound is. But regardless it's too late now to do anything more but monitor the healing. And it won't hurt anything besides him having a little bit larger scar than he would have. So I would just continue to keep an eye out for signs of infection(redness, swelling, lump, oozing, yellowish/white discharge).
