If I were in your position, I would make the opposite decision; it would be beating jus (seriously, I don't understand what possessed them to spell the name of the series this way to this day) and washing clothes all day, every day.
IIDX arranges all its songs in folders; the SPADA folder, containing songs that premiered in that version of the game, is the one open by default. You can tap the name of that folder or press a black key to close it and go back to other folders. There are folders for each entry in the series (1st style all the way through tricoro), folders with alphabetic ranges, folders by difficulty, etc. By default the songs in each folder are arranged in difficulty order for the difficulty you selected at the time you opened the folder; this sorting method can be changed but I honestly can't recall how. If you change difficulties, you can just close and reopen the folder to resort it.
The levers affect the sound coming from the machine when the equalizer is turned on, just like it would on a typical audio amp. There are some fun things you can do with it also; for example, one of the equalizer options allows you to change the pitch of all sound coming from the machine. Most players just use it as a means to make the machine louder, though.
Also, one more note about online stuff (and you -are- playing with an eAmusement card, right?) - in HK you are likely playing on Konami's official eAmusement network, which, aside from the Round 1 locations in California, does not operate in the US. Most eAmusement enabled machines in the US actually run on a third party network called Programmed World (Round 1 is the sole exception; they are a Japanese company that made arrangements to run games in the US under their Japanese account). As such, you can use the same card for both networks, but no data is shared between the two. Konami's network also has limit for how long they preserve data for inactive users before wiping it all, so if you are not returning to an area near a Round 1 you are probably going to lose your account a couple months after you leave HK. Programmed World has no such limitation.
They would need a whole new run of controllers, and I can't see how that would be worthwhile. If they really wanted to they could partner with another hardware manufacturer and use that to defray some of the cost, but I suspect even then it wouldn't be worth it. (Then again, Hori makes full-sized controllers for Project Diva, and that is just as niche... but the game is still playable on a controller). I think it would do OK sales wise even with a small playerbase, as they could throw an absurd amount of DLC at the game (much like how their iOS games are sold), but the controllers are a big problem.
