First, let me say that I think you're making a good choice in vendor. Buying a Dovo from SRD is a very good option especially with the lifetime honing offer. I personally don't own a Best Quality DOVO because I started with a vintage razor that I was able to get cheaper. I do have a DOVO in mother of pearl that I absolutely love, though.

5/8 or 6/8 are both equally recommended for new guys, and the only real consideration of the point type is that you just have to be mindful of that spike or square tip all the time. If you aren't careful, you will end up slicing your cheek with a square tip while shaving other areas (happened to me several times when I was learning). That's the main reason that many recommend a rounded tip for new shavers.

Strop: Personally, I'd change the option to get the best strop available, and also get a cheap strop like a Filly ($20 from rup razor) until you get the hang of stropping technique. Then you'd be able to get the most out of your strop from SRD without as much risk of damaging it.

Good luck, and enjoy the journey. Welcome to SRP too
