Coming Back To FFXI Break Since August! Advice Plz

Hello everyone,

I stoped playing FFXIin August last year, and i decided today, ill revive my Character, and im updating FFXI atm.
So i need some help what to do first and some tips on how to do it,so i thought this is my roadmap.

1. Get MogSack
2. Buy Bonanza Marbles :D
3. Doin LevelCap quests because im capped at 80.
Should i farm crests my self or is it worth shouting?
Can i get them in Abyssea along with merits?
4. Level up and start doing Abyssea Missions to get Atmas.
Can i solo some missions to be able to get 3 atmas in teh end?
Shouting for Abyssea missions?
5. Getting Atmas and Key items and seals for armor.
Shouting? getting a static?

So what else should i do first?
Whats importand?
I really feel far behind and im not sure if i can catch up, so any advice and help is highly appreciated.
Thanks

THX!
I just whant to get PUP to cap again, then i think about getting something more "whanted " up like THF WAR MNK or WHM but i wonder how do i level a job thats around 50? Abyssea?
Then i can be maybe join a decent LS.
Edit:
Oh and btw, is dominion any good?Worth doin? i really dont have any cruor :/

If you can't chest-*** your level 50 job, someone suggested doing dominion OPs on one job then switching jobs and turning them in on the low level job. It's awfully time consuming, but it'd get the job done.

Time extension abyssites noted, thx good tip
I need to read into these Dominion ops stuff
