See the PostGIS documentation, in particular Chapter 4 "Using PostGIS":
http://postgis.refractions.net/docs/ch04.html
(The site isn't responding right now; hopefully it'll be available
soon.)

There are two problems with the geometry string: the syntax error is
due an extra comma in the second pair of coordinates, and coordinates
should be (X Y) therefore (lon lat) instead of (lat lon). Try this:
insert into routes_geom values(1, 'J084', GeomFromText('LINESTRING(-121.00 38.20, -118.00 38.20)', 4326));
You might wish to subscribe to the postgis-users mailing list if you
have additional questions.
