You can select on highway, but be warned that will also give you  
highway=footway, and highway=cycleway.  It just searches for the word  
highway occurring and grabs everything with it.  The search/filter  
dialog includes a number of examples, the best way to learn about it  
is play around with it.

I see Richard already recommended geofabrik[1], cloudmade also makes  
extracts available [2].
It looks like Sweden is ~120 MB compressed, but I don't know what it  
expands out to.

I'm not sure if JOSM can or not, I'd give it a try and see.  If you're  
worried about size, cloudmade has just a highways extract that is  
about half the size.
You might look at Osmosis[3] to filter data before you edit it with  
JOSM.  In general, the wiki[4] is a wonderful resource, although at  
times you have to explore quite a bit to find the answer you're  
looking for.

Good Luck, and let me know if you've any other questions,
