Even if you can't read any of the numbers, if the boiler doesn't go out, doesn't overheat, and heats the house...it might not be prudent to mess with it at the start of the heating season. With that said, here is the info you asked for.

Yes. Intermatic units are available for about $100. They may not be of the same built quality, but they seem to be good enough for most people. Model C8835 is a 30 minute timer, C8865 is a one-hour timer. Sometimes used ones or "new old stock" comes up on ebay. Tork also makes some timers that will work, but I don't know the model numbers off-hand.
Another option is to build your own timer. Forum member "Vermontday" uses a device called a LOGO, and you can read about it here: EFM 520 Install with skid/bulk bags feed
If using a laptop to program your timer isn't your style, you could also build a mechanical timer using a plain electrical enclosure and repeat-cycle relay...the nice part of this one is you can get a relay with an adjustable (adjustable by a knob, not a laptop
)cycle length. If you want to run 2 minutes every 45, that is possible.

Not that I'm aware of. Honeywell and Hydrostat both make triple aquastats with a digital readout, but the Hydrostat is my favorite (easier to adjust, and it can function as a low-water cutoff).
