Anything out there besides chipguide.com?
The short answer is, "No." Not to the extent you're looking for, at least, and not in a single location. Information on chips tends to be relatively spotty due to the various natures and interests of the industry. The casino, clandestine, and home markets all have different interests, many of which don't intersect, and some of which squarely oppose one another. The PCF crew and those over on
www.thechipboard.com are probably two of the most knowledgeable communities on chips at large. While the information is plentiful between those two groups, there's generally little need/profit into organizing it into a searchable, easy-to-navigate resource.
That being said, the site that
@links_slayer posted is the first one that came to mind. Lost of great info there on molds. You've already listed chipguide.com which is indeed a wealth of information, albeit frequently incomplete and occasionally inaccurate (I state this mainly in reference to its data on illegal casinos - the clandestine nature of the illegal sites often times make it difficult to get accurate/definitive/complete information). The other link I would guide you to is...

This is a really solid list of home, fantasy, illegal, & tribute chips put together by the primary casino chip & gaming token collectors club. They have an acronym for their club that is approximately 6.02x10^23 characters long. I don't bother to remember it. I just know it's there, and they help keep our hobby going.
I quickly get overwhelmed
In the world of chipping, almost nothing is quick. This game requires patience - almost every aspect of it. My best advise to you other than "Get samples first," is that for anything good, be prepared for a year's worth of waiting from concept to getting all the sample sets out the door and finishing the oiling. For just diving in, learning the ropes takes time. For your first good set, figuring out what you want takes time. Gathering samples takes time. Finding/waiting for your chips to arrive takes time. When going for customs, getting art lined up takes time. Saving up enough money/paying off the 2nd mortgage might take time. Waiting for your chips to be produced/shipped takes time.
You get the point. Just take in the information as best you can & try not to get frustrated. In time you'll learn all the ropes.
Most of us have been where you're at, and I greatly empathize wanting to have all the knowledge at the ready. Unfortunately it doesn't work like that in the world of chipping, but the beautiful thing is frequently you get to a point where you really learn to enjoy and embrace the search for knowledge, the journey to a poker meat-up, and the wait that ensues after your customs are paid for.
