Hi there. best place to start is the Fantasica Encyclopedia topic with lots of hints for you. always first read the sticky topics...
First and foremost Time elixirs (TE) and Potions (POTS) are the ingame currency of choice. Don't use them while questing or training... you can use personal ones denoted by (p) in event rewards as they can't be traded. You can also check your inventory in your ingame profile to see how many of each you have.
Good luck
