The Tarantula Keepers Guide is a great resource for breeding but doesn't cover specific spiders, example: Stromatopelma calceatum, Brachypelma smithi, Psalmopoeus irminia et cetera, and I fully understand why it can't give you breeding advice on certain spiders (Probably space constraints or lack of time et cetera).
Brachypelma species are pretty much straight forward, just chuck them in and they get to it. It's getting an eggsack that is hard. I understand fully all your concerns, but just remember as well, not everyone has access to tarantula books and not everyone is going to go through 3000 Google pages to find a few tid bits on how to breed G. Pulchripes or P. regalis (Even though there are probably thousands of pages with good info for these mentioned species but you get the idea)
Personally, I couldn't get any good info on breeding S. Calceatum and thus have decided to wing it. I'll try various things but I made a nice natural setup for my female and the males been living in her enclosure for close to a week so hopefully something has happened during the night.
Concerning incubators, not everyone has the time/money/skills/all of the above to build a mechanical mom. I myself can't and won't and will just use the Hummack method if I get any eggsacks.
Concerning the slings, this is also very important. If you can't get small enough crickets or roaches, don't let them go hungry, just chuck in some normal size (and dead) crickets or roaches and they will eat what they want from it. I do the same with all my slings.
Concerning annoyance: Not particularly, no.
