I don't know what the administrators will be doing to advertise the bots. They have put a tremendous amount of time in on this, to come up with 60 bots with varying skill levels. So, I imagine they will heavily describe the bots at some point in the forums or articles. I must say though, It was surprising to see 50 + bots hitting over 3 days of time with only a small blib in one of the posts, mid-summer, that they were coming on-line at some point.
Whatever the admin people will be doing, I have been playing the bots on a daily basis and am working on posts which detail each game, so the members can gradually accumulate data and info on the bots. I like your idea of a shortlist. I will probably include a small blib on each one which I haven't played. I can send you a link to the posts as I finish them, if you like.
On your point #3, I have noticed the same thing. I have had several games where the bots or even Komodo have come out very strong in the opening. After fighting them off and barely surviving, many of the lower levels will weaken considerably, giving me the game in simple flubs. Its almost if they are programmed for a 1800 + rating level in the opening, then at some point mid-game, turn down to a 1000 rating level or less. Perhaps, that is the way the bots and Komodo can be reduced in their ratings. better than the lowest levels with flubs all the way, but not great play all the way, either. I would prefer a consistent level of ability coming from the computers, but as a character in the original Star Trek series said: "the air is air ... what can be done?"
and a machine will always be a machine, but with a so evolved ai, i can't imagine that they cannot reduce depth, making the machine to make inaccuracies, and not to shamefully blunder... I know i play komodo as if i am playing a bullet, despite the time control i play... It plays quickly, i play in a sec... 
But it wins for me twice in 15 moves today... I'm not a master, but i don't play as badly too... Like you said, seems 1800 and then drop to 1000. Great great openings, even when it takes the queen right away, and i think how i'll punish it, and sometimes... well, let's say i don't pretend to analyse that games... too strong for 1300...
Ok, i play a lot with komodo and i'd like to make some questions that i think it will be general interest.
1) There is a list of komodo standard (initial/supposed) ratings?
2) It seems that komodo plays better when it have higher rating. Let's say komodo 10. If it have at a moment 1400, it plays better than when it have 1300. It is psychological or it is true?
3) komodo 9/10 seems to play way better than its rating for about 20 moves then make a blunder that not even a newbie would do. It is normal? It is supposed to komodo emulate human moves, way better than stockfish, and that doesn't seem very "human" to me. It should make several inaccuracies not a killer blunder if i survive some time...
4) There are push downs/ups for komodo levels when they invert order, like 9 higher than 10 for some time?
5) After some games with the bots i feel that all moves are the same between games. It feels that if i write the game down, i can play all the same, with no variation. It is true, or only my feeling? If it is true, can't you give a more random responses for the bots?
6) When the 60 bots will be available? There will be any shortlist describing each abilities?
Hope someone can answer me! Good chess!
