Have you read http://wiki.openstreetmap.org/wiki/Buses , 
http://wiki.openstreetmap.org/wiki/Public_transport#Buses and 
http://wiki.openstreetmap.org/wiki/Proposed_features/Public_Transport 
(which I think should be featured more officially, not in a proposed 
features page)?

The way I do it (and in no way am I saying it is the only way or the 
correct way to do it, but it seems to hold up fine) is make one relation 
for each seperate destination (usually two: a->b and b->a, sometimes 4: 
a->c->b, a->d->b, b->c->a and b->d->a) and group those relations in a 
master relation. The master relations get grouped in a (master-master) 
relation that holds all buslines for one concession.

Each bus relation has all the ways the bus traverses, and if it 
doublebacks on itself somewhere, I add the way twice. JOSM will 
highlight those ways in red in the relation editor, is that the warning 
you describe?
Then add all the stops in correct order with role "stop". If you order 
the ways and nodes in the relation editor, JOSM will put the stops 
first.
I believe officially you should only add nodes with 
"public_transport=stop_position", but in absence of those I also add 
"highway=bus_stop" (or even tag those with 
"public_transport=stop_position" which is not entirely correct).

As an example, see https://www.openstreetmap.org/relation/398909
