At least 36 changes is recommended for EOD washing. So, 6 more of something -- could be prefolds, workhorses, flats, whatever.
Are you doing cloth wipes?
Grandma El's is great but I would save it for the more stubborn rashes/redness. It might be nice to have something like CJ's or Magic Stick or EMAB handy, too.
Do you know what detergent you are planning to use?
Basically what the others said about a few more changes and potentially some smaller covers. I'd get more workhorses if you want to stay frugal. I loved those. I also liked having a few AIO's (blueberry simplex) for the diaper bag. Also CJ's.
I would recommend having a few different style covers. Turned out that I hated our Thirsties, but loved Rumparooz nb, Flip, Bummis super brites, and Best Bottoms.
I just had a 5lb 14oz baby. My thirsties no where near fit 11 days after. Also do not get econobum nb. They are the worst! I just threw the 2 I bought out because I would feel so bad selling them to anyone!
Proraps and Imse Vimse both have preemie and NB sizes. I'm not sure how the NB sizes compare to other brands, though. I do remember that we had an NB Prorap in our diaper trial and he outgrew it before the Thirsties size 1 and Bummis Super Brite.

Suddenly my life doesn't seem such a waste,
It all revolves around you.
How many wipes do you recommend? I will most likely make those myself.
I'd start with 3 dozen wipes, you will go through them quickly, but you'll also be washing regularly.
And 36 is recommended, but I did fine with 24 (my pure and naturals didn't fit well at birth). You just need to wash more often.
