You post some very good questions. Some of the information on products listed in the Care post you mention may be slightly outdated, since this post was last updated in 2015. I've been collecting data so that HCA can update this Care post, and I've already found one discontinued product and a few reformulated ones. Sounds like the TopFin product you're asking about has been reformulated. From the description, it sounds like the TopFin water conditioner now treats for all the main contaminants (chlorine, chloramine, ammonia, heavy metals) listed in the Water guide, so it should be fine to use, in my opinion.
Now the bit where it says it "helps" rather than actually does something... well, a lot of these products work best and are designed for use at a certain temperature or temperature range (general fish tank conditions for the most part), and the amount of the TopFin product needed to treat your water will depend on how much of each chemical or substance (Chlorine, chloramine, heavy metals, etc) is in your original water. Also, most water conditioners precipitate out the heavy metals, by reacting with them to form a non-toxic compound that can be removed by aquarium filters. So technically, the heavy metals are not removed from the water, but they are made inert, in a sense. That may be why the label states it "helps" rather than "removes". You can contact the manufacturer for more information on usage and request a safety data sheet, if you want to. You can figure out how much of each chemical/substance is in your original water by having it tested (some tests you can do yourself). In the USA, your municipal or city water department should be producing a report to let you know what the yearly average amount is for everything in your water that is not strictly water, so you could look at that. Or you could just treat your water according to the TopFin package instructions. Putting a bit more than the package instructions should be fine too.
When I learned that my All LIving Things water conditioner didn't take care of all 4 things (ammonia, chlorine, chloramine, heavy metals), I threw it out. Most folks on here use Prime by the manufactuer SeaChem. It treats for everything, and has a lot of really helpful and useful info on their website. There are other good products out there that are probably comparable to Prime, I just don't personally know about them yet.
Slime coat is not needed for crabs. There's no evidence that is is harmful, though, that I know of.
Best of luck!
