As for connecting all those other stories in, here's my notes that I commented to someone on twitter. It's a little chopping, because it was broke up for twitter:

I just went through the list of out books and the only ones I could not easily find connections to were OH, PtR, and SK. The connections may be there, but I did not find them at a quick glance through. Here's the list of connections I did find, but be warned, it's long.

Characters from MW cameo in RoE, LH, RCD, PM, WT, TRR, and TF. Another character is the sister of a character in ES as well as there being a character from MW mentioned in ES. Characters from TF cameo in THoBM, RoE, AME, and LH at the very least.

TRR is a spin off of both TC&TF and RoE. It is mentioned as factual in HSS. In addition to that characters from LH cameo in HSS.

IL, BB, and NB are acknowledged to be in the same universe. Characters from IL cameo in NB and back and forth between NB and BB. VoS references Vampires in NYC, although the two talking don't think it's real, they are talking about someone who does.

There is a theory (unproven) that one of the characters in LH is the nephew one of the characters in HftH mentions getting a gift for.

A character in D&D had the title later held by a character in TRR, although that character no longer has the title, so it may go to someone else. This would connect that back to the main batch.

AtV has the origins of the crystals seen in Hero and ES. The ending of Hero appears to have the MC crossing into the world of AtV prior to the explosion that caused all the different types of aliens. As ES is connected to the large batch of them at the top, this makes things complicated, but a character in ES is definitely the daughter of a character in RoE/LH and a character in ES is definitely the brother of a character in MW.

TE references things that are real in IL and LH as existing in their world, especially the reference to IL as being on the west coast, which is where IL takes place.

TH:M connects back to all sorts of things including: LH, AME, RCD, RoD:ABBR, RoE and PM.

A character from Platinum is mentioned in The Senior if you take the right path in it. At least one other character is from AME. A character from RCD is mentioned in Platimum.

The HSS and Hollywood U apps are acknowledged in the same universe as well as having some crossover in certain story lines. HSS and RCD appear to be in the same universes as their app counterparts.

Characters from LH are either cameoing from or have cameos in MW, TF, PM, TH:M, RoE, TRR.

A character from BB is the counsin of a character from ACoR, although since this is only mentioned in BB, it's possible they aren't in the same universe. It's also possible it was relevant to the story, so who knows.

And that's what I came up really quick.

And there you have it, a quick over view of a quick look at all the connections I could find without searching very deep. If you have questions about specifics, let me know as I know this is not very detailed.
