Eli5: if the lawsuit against Obama proceeds, what court is it heard under? How does this work?

It probably doesn't get heard in any court.  There is a requirement in the federal judiciary that the aggrieved party (i.e. the Speaker of the House) can show harm was done to him (i.e. by Obama signing executive orders).

Keep in mind that matters of "unconstitutional behavior" are part of the impeachment process, and cannot be pursued in any court.  The impeachment process is completely in the hands of the Congress.

Furthermore, even if it were ruled that the Speaker had standing in federal court, it is unclear what remedies a court could order... but we're going a long way down the Speculation Railroad when we don't even know the grounds on which Boehner intends to sue.
