They really left out a lot of trailheads. In addition to those indicated on that map you can access unit 54 from the following trailheads:
Horse Ranch Park Trailhead
Lost Lake Trailhead
Swampy Pass Trailhead
Beaver Ponds Trailhead
Mill-Castle Trailhead is actually three separate trailheads(Lowline Trail, Mill Creek Trail, Little Mill Creek Trail)
Zigzag Trailhead
April Gulch Trailhead
Beaver Creek Trailhead
Sun Park Trailhead
East Elk Creek Trailhead
Lion Gulch Trailhead
Coal Creek Trailhead
Big Soap Park (several trails start there)

There are additional access points on the west side of the West Elk Wilderness but they're not in unit 54.
