Final Fantasy XIV only has PvE servers
1.So this game only has PvE servers. Some are labled "roleplay", some are labled "legacy", but effectively everything is PvE centric. There is PvP as Enkidoh mentioned, but its basically separated into its own instances and accessed in its own way. As for Siren, i dont play there but it does appear to be a low-mid population server. One thing this game does though is that for a lot of content it emphasizes the data center rather then the server. When you que for a dungeon or other instance, it matches you not just against your server but all the ones in the same building. Siren is in the Aether center, which is one of the highest population(possibly THE highest) that they have. So while you may not see quite as many people, you are still potentially being matched against a large population. Otherwise, youre still pretty early in so you could potentially switch servers and make a new character if you prefer that option(or pay to transfer your existing character to one of the busiest servers).
2.Effectively there are almost no limits. Your one character(regardless of starting race gender and class) can unlock and level up to 60 all 24 classes currently in the game(13 combat, 8 crafting, 3 gathering). As Enkidoh said, you do need to complete the level 10 quest from your starting class to unlock the system. After that you can go nuts. Now i said there are "effectively almost no limits", which obviously means that some small limit exists somewhere. There are 2 you will come accross if you try to do everything. First limiter: having appropriate gear for 24(and possibly more after the next expansion) classes takes a LOT of inventory space. Getting good gear for multiple classes also takes a lot of time. Now obviously some classes can share, but you need to keep them at similar levels for that to be effective. Second limiter: at the very top of the crafting system(as in, doesnt matter before level 60) there is a "specialist" system that unlocks extra recipes for some classes. You can currently only have 3 of them at a time(you can switch them with a little work, but cant have more then 3 at a given time), so this limits you a little at the highest level of crafting(if thats your thing).
Aside from those considerations, you can do it all on one character.
3.The system in this game is called the "Glamour" system, and Enkidoh covered it well. Theres also a level 15ish quest in Western Thanalan that unlocks the option to dye some of your gear(not everything can be dyed) different colors - another way to customize your appearance and available much earlier in the game.
ff14gilhub:I think game parser should be added to FFXIV
Let me start off by saying that all adding an official parser would do is put console players on more equal footing with PC players, most of whom are already parsing.
FFXIV Dungeons are a good start to have mid-core difficulty
To which it was insted of DPS it was changed to mechanics but now A6 Was a static killer A7 was a wall and A8 was very very difficult to where not alot of people cleared it.
FFXIV Patch 3.2 spoiler warning
The A Realm Reborn PR site specifies that the First Umbral Calamity brought an end to the Age of the Gods. Likewise, the Dusty Tomes claim that man was created to wage the Gods' wars after they left at the beginning of the cycle of the Eras.
Dragoon or Black Mage for FFXIV 3.4 patch
Dragoon also brings Disembowel to the table. Most/All raid groups have a Bard or a Machinist will see their DPS increased from it.

ff14gilhub:Are Relic and Diadum anti-raiding tools?
I also really do enjoy AS1, and the only reason I dislike AS2 is because of enemy collision. The static I am currently in has just cleared AS2 and beginning ThEX instead of AS3. I love raiding in this game and find it very satisfying.
