GL on BST when you come back. There's plenty of good advise from good BSTs here so I won't be adding too much.
I found Alla quite helpful, it seems low on the 'dipshit' factor that you may see in some of the other areas. Also ffxiclopedia has been very good in answering questions I had.
Jug pets are not so helpful in solo exp situations (unless you in trouble), but its really useful to not only understand where they are beneficial but which one to use. BCNMs, Promivions and other level cap stuff has its place with juggies for sure. It wasn't until I got to 55 and up I really started to leverage jug pets for other things besides level cap stuff. Even @ 75 Crab Familiar is my most used juggie. Yes, it caps @ 55, but I use it much like a SMN uses Carbuncle. If I'm running across a zone, say Bubu, I have a Crab out smackin' gobbies on the way. It's how I have a 100 gil pet return 10X its investment.

Now that I'm 75, I use Carries for farming from low-EXP mobs. For example, when farming Buffalo in Uleguerand Range, there's no way I'm charming local pets to do my bidding. It'll take too long, and I'll pull hate on the 5th hit. Get to know your juggies here:

End game stuff as BST is fun. Your ability to widescan, handle links/adds, pull, charm-kite etc etc makes you a welcome addition to an
informed party or alliance. You may have to inform the public at large about why you kick ass, but once you get a shot, you have the ability to do so.
Lastly, I'll let you in the first rule of BST Club. No beers (or wine/liquor/pot/LSD/pr0n) while getting serious experience points. It's a hangover that you'll regret, trust me.
