Here's one option, it's a SR (Sakae) forged crankset that has a 86 BCD (bolt-circle-diameter).
Forged means that the crank-arm and spider are one piece. Your current crank is swaged, meaning the arm and spider are two pieces pressed together, this is okay but not as strong as forged.
The BCD of this crank is rather small allowing for smaller inner chainrings. This is important if you will be riding longer distances on hilly roads.

One more question I'm thinking about the cranks you picked out, I think I understand you suggested them so I could go smaller with the chainring down to like a 32. If I'm totally content with a 52/40 chainring do you think there are better SR Apex options on ebay?

New chainrings for that crankset are, well, they're expensive. They simply don't make them anymore. In my opinion those cranks shouldn't have been recommended. If you want to drop to a set of rings with fewer teeth it may cost $70 plus shipping/tax.
Has anyone purchased from this site? https://store.bicycleczar.com/category-s/420.htm
It's the cheapest source for small rings this side of the Atlantic that I could find. Anyone else know a good source?

Stronglight quite literally makes them new for Spa Cycles. Cost is reasonable, shipping is reasonable
Unrelated my comment above, the comments of “shipping someone back to where they came from” are completely unnecessary.

Well, that's good news. It's still a bad crank recommendation considering there's only one manufacturer left compared to....how many for 110 BCD? And they're across the ocean. And expensive.

Pretty sure he's cooking his Yelp reviews, pages and pages of all 5 star. Forgot to mention when he was wheeling my bike back he bumped the dropbars on an open toolbox drawer bet you my tape has a gouge.

Search "130 bcd 40" or "130 bcd 52" in ebay you'll see what I mean. 42T is much more common though, if not low enough, you could always go with larger cogged freewheel

If you only need 40 as your lowest, I would look for a crank with a 130 bcd, much easier to find chainrings for them. Shimano 600 is a common crank which has 130 bcd.

Quick question, I got my cranks put on less than two weeks ago, this morning I noticed a chainring bolt MIA and the other bolts pretty loose. When the cranks arrived from ebay I noticed they were loose then and I told the bike shop guy about that and he said he'd take care of it. I'm getting in touch with him shortly to see what he says, just curious if it is possible that he did tighten them and all 5 bolts somehow came loose? Also what is the etiquette if he tries to charge me to replace the missing bolt? I don't want to be an ahole about it but I think a free one is in order.
