haha Its okay. Bad English. Smad English. As long as I can understand you then it's all good.

To find the Cactuar esper, you need to go the desert in near Miranda in the world of Ruin.

EDIT: I checked out Gamefaqs for a more precise location and here's a bit more...

Talk to a man to the left of entrance of Maranda to learn about Cactuars. Go into the desert and slay 10 Cactuars. Go to the SW corner of the desert and you will fight the
Gigantaur. Defeat it.

And for Gilgamesh, you go to the auction in Jidoor and bid on the Excalipoor. You need at least 500,000 Gil with you. If you win, you'll fight him and need to defeat him in order to obtain him as an esper. Hope this helps.

yeah, once you get the excalipoor, take it to the arena and wager it with a strong character. you fight some impish thing and get the merit award. Gilgamesh appears and says he will take the sword from you. Having ultima and a celetriad helps...a lot.
and just to reiterate--
WHERE IS THAT LAST FREAKIN DRAGON AT?!?!!? SOMEBODY PLEASE TELL ME BEFORE I GOT UTTERLY MADDER THAN I ALREADY AM!!!(which is near impossible)
