Flooring project help

This is my first time posting here and was wondering if I was on the right track with my flooring project.
I live in Southern California and just bought a 1,200 square foot house that was built in 1954. The house has a raised foundation with diagonal plank sub flooring that sits on 2X8 joists that are spaced 16 inches on center.
The plan is to lay 3/4 inch OSB over the sub flooring to help level/strengthen the flooring before I install luxury vinyl planks over it. I'm planning on staggering the boards with 1/8 inch pace between them and screwing them down every 6 inches using 3 inch deck screws. The issue is, I keep getting conflicting information on wether or not to use tongue and groove sheets and wether or not to also use glue. Any pros and cons between using nails, ring shank nails, or screws?
If anyone was any insight on this or know any good sites with information or possible videos, could you please let me know?
Thanks in advance

Thanks for responding so quickly.
I have since decided on not glueing, and that tongue & groove isn't necessary (since it's not subfloor). And normally you would run the boards perpendicular to the subfloor, but since mine consists of diagonal boards, it doesn't seem to matter. So, should I run the boards perpendicular to the direction I plan to run my vinyl planks? Does it matter?
Maybe thinking of using 5/8 CDX instead of 3/4 OSB (can't seem to find advantech). And I thought screws would be better than nails. I'm looking to secure this floor as best I can while I still have access to it, I'm not exactly looking for the cheapest/easiest if it's only going to act as a "bandaid" to a potential future problem. It seems everyone is agreeing with my plan, just iffy on the materials. Any thoughts on wood, thickness, and fasteners (type)?
Thanks again
