For future reference, broad axes are pretty weak compared to 1-handed maces or swords. Axe users should almost always go 2-handed unless you find a particularly good artefact 1-hander like Arga.

On a normal sized race wearing armour with a non-zero ER, you need 5 shield skill to eliminate the penalty for using a buckler, 15 for a regular shield, and 25 for a large shield. The skill required for a large shield is rarely worth it on a normal sized race (the penalties are lower if you've got no ER from armour or you're a large race or formicid, and higher if you're a small or tiny race).
In this case, your biggest problem with your defenses isn't the fact that your best armour is plate, it's that your armour and dodging skill are really low for a level 18 character. You should train armour much more than that to get your AC up.
