When you hit the 'download' button in JOSM the default area it selects
is the bounding box of the screen. Just hit OK and it will download data
for the area covered by the GPX data visible on the screen at the time.
There is no need to go off to another map to locate the download
co-ordinates.

If you've covered a large distance in your tracks (say 10+ miles) then
you may not be able to download all the data at once. Just zoom in to a
smaller part of your GPX and download just that area initially. Then you
can pan the map a bit and downloading again to grab some extra data and
it merge with that already downloaded. 

Occasionally JOSM fails to join up the multiple downloads correctly so
you may have to save the .osm file, restart JOSM and reloadit.
