Wiggling cranks

Usually when you get new cranks you have to tighten them A LOT but after
a few rides they stay tightened. It's like breaking them in.

Could anything else be wrong?

First off, there is a recommended procedure for tightening cranks that
includes grease and a torque wrench, while excluding hammering. Do a
search and thou may find. See if that helps. Alternatively, it might
be that when you rode with loose cranks, you damaged not only the
cranks but also the taper on the hub. If so, too bad - the only good
solution is a new hub.

Also, what other
regular maintenance jobs should I be doing, and how often?

The crank - square taper interface is surely the most important one to
check frequently, as it tends to loosen, and the results can be
'dramatic'. Others include:
* check your pedals for tightness
* check your seat bolts for tightness
* check your tyre pressure every few weeks (but you will notice that
anyways)
* rotate the tyre with respect to the rim by 1/8 to 1/4 revolution
when it develops bald spots, e.g. from idling.

When riding trails on any square-taper unicycle (like my 29er), I always
give the cranks a tighten before heading off. So for the time being,
just remember to tighten them once every day you ride, and you should be
fine for quite a while.

But yes, if the tapers are damaged from lots of loose-crank riding, they
will tend to keep coming loose more and more easily, until you replace
the hub.
