A couple Questions

[Obeliske]

OHHHH those things! Yeah I've done those each once each as well.

I realized this morning I aught have been doing the roulette :P random daily dungeon is something I'm gonna have to start doing every day.

The challenge log... I think I read about that in one of the tutorials I'm sure I can find it but what exactly is it? and is it worth grinding?

Also as a side question is there a /played command ingame? Something that tells you the age of your character and how long you've been playing that one?

Also back when I first started the toon I read something about an achievement vendor having all my titles and stuff like that where do I find him?

The challenge log is VERY useful. It resets weekly (and you don't need to do anything special once you've picked it up, you'll finish stuff automatically after Tuesday reset) and you get tons of exp for completing the challenges (5 FATEs in different regions, 20 levequests, stuff like that...nothing grindy) - checking on my level 30 BRD, I would get 24,375 exp for each of the two FATE challenges (Highest rating in 5 FATEs in 5 different regions & complete 10 unique FATEs). The exp adjusts to your level - for the same challenges, I'd get 48k each on my level 40 PLD and 5.3k on my level 15 lancer. You unlock it through the level 15 quest "Rising to the Challenge" at Limsa Lominsa Upper Decks (x11,y10) - the NPC is I'tolwann.

There is no way to see in-game how long you've played.

The achievement vendor is in Apkallu Falls in Old Gridania. His name is Jonathas, Master of the Rolls. However, you get titles immediately upon getting an achievement - they're in your character menu under the profile tab. You click the little triangle to the left of "Title" at the top of that tab.

OHHHH those things! Yeah I've done those each once each as well.

On each class, or just on one of them? If you've only done it on one class, you should do it on the others, too - especially the lancer. It really helps at those lower levels!
