I'm going to agree on the first point that ackeight made. You would be VERY close to the tower if you were to follow the glideslope all the way down. However, with the final stepdown on the localizer located after you pass the tower, then you still have your obstacle clearance.

As for the second question, from ULESS, ackeight is correct in that it is 183 Magnetic course to COXOD and 7.3 nm between the two, however, from there it is another 4.5 nm to LAMMB (the intermediate fix - IF).

Hope that helps.
