Hi there, welcome! The forum is still being worked on, so you may not get too many responses yet!
In the meantime, I recommend checking out the sections on bonding, diet, etc, as I think some of that info will help you plan the approach you would like to use for bonding. If you search “bonding journal” on this site you will also find lots of member’s experiences that will help you know what to expect.
I would recommend keeping at least one room of your house bunny-free so that you have some neutral territory to work with during the bonding process. You are correct that males can be neutered younger, I think around 12 weeks is average. Females it’s usually around 6 months, but varies a little by vet, so you should communicate with your vet about the age they recommend. Typically it’s good for buns to be housed near each other before bonding to allow them to get used to each other. I don’t think the female would be stressed with having the neutered male near, but you can see how they do and adjust their housing as needed.
I don’t have too much experience with young bunny diets, but there are usually young rabbit specific pellets which contain more alfalfa, and plenty of grass hay (timothy).
