Monk is my main in FFXIV and I have recently cleared Turn 1 of coil, so while I am by no means the best Monk in the world, I still figured I could share some of my ideas with you that might help.
For macro's, this is a good one: http://na.finalfantasyxiv.com/lodestone/character/2825484/blog/232247/
It will basically include anything you're going to use in your basic rotations, so all you'd have to do is keep your DOT's up.
As for cross class skills, I'd reccomend getting: Fracture 80 TP (Marauder Level 4)
Delivers an attack with a potency of 100.
Additional Effect: Damage over Time Potency 20 Duration 30. Invigorate 180 s Cooldown (Lancer Level 22)
Instantly restores 300 TP Blood for Blood 80 S Cooldown (Lancer level 34):
Increases damage dealt by 20% and damage taken by 25% for 20 sec
you can pick two more, so have a read of this guide here and decide for yourself what to get: http://www.ffxivrealm.com/guides/monk-dps-guide-v2.14/
I sometimes use Bloodbath and Foresight for defence and self healing. It's not much, but it can help keep you topped up from low damage unavoidable AoE's and it will save the healers at least a little trouble keeping you topped up.
As far as general tips goes, learn to dodge really really well. Since we're melee we tend to stand in a lot of red circles we need to run out of. I quite often use Fists of Wind instead of fire, since it helps move out of harms way quicker. I'd rather do a little less damage than get KO'd :P
That's pretty much it really... at least from my experiences anyway.
