To complete mission 2-1 take the crystal to Cid in the workshop on the first floor of Metalworks in bastok.
as for mission 2-2 get the mission from the gate guard, go to the AH, buy a lizard egg (to obtain it from Dangruf Wadi, as sugested you need to be lvl 30 to solo due to goblin muggers, leachers and ambushers in a lot of numbers so you can't avoid links) then go to metalworks and to the presidents office and give the egg to Santor Alois for a cut scene and mission complete.
for all Bastok missions go
here
If you ever find you can't get any missions, trade a stack of crystals (earth are the cheepest) to any gate guard that casts signet on you and you status will go up and missions unlocked.
P.s. as your playing now I would change your profile to show this and what server you are on current job levels etc. so we can help you more knowing your stage in the game.
