Parties comprised of members that can effectively attack from a distance (BLMs, RNGs), with the appropriate support jobs will do very well here. That being said, a regular setup will still work, although there won't be able to take as much advantage out of the Worms' immobility, although there isn't too much in terms of inaccessible Land Worms due to surrounding aggressive mobs.
Walk up and down either one of the red paths given, killing Land Worms as you come by. The top map is situated right as you zone in from the Zeruhn Mines, and usually has other people solo'ing the Land Worms there. The second map is on the opposite end, towards the Eastern Altepa Desert zone line, and is generally empty, although you will have to be on the watchout for Air Elemental pops near the stairs.
The third camp is between the two- simply continue walking onwards from the first camp, and move towards the point marked "H" on the map. Be careful when crossing the bridge though, as mobs can still aggro you from down below.
One trick you can use to prevent massive amounts of damage to your party is to have your "tank" stay out of melee range, using Provoke to and ranged attacks to hold hate from afar. Note that this person doesn't actually need to be a tank class- RNG/WAR works very well. This way, other members of the party can freely melee the Land Worm without fear of retaliation, and Stonega is contained to just one person.
Keep Barstonra up at all times to minimize the effects of the Worm's spells, and if your White Mage is level 15 or above, keep the Land Worms Silenced to minimize their damage output. As they say, a Silenced Worm is a dead Worm. By 17-18, a lot of the Worms will con Tough to members, so just mow down any Land Worms you come across.
