Some more advice... Things you'll want in your pantry:
Fish Sauce
Light soy sauce
Sweet soy sauce
Black soy sauce
Oyster sauce
Shrimp paste
Dried shrimps
Tamarind concentrate (liquid)
Sweet pickled radish
Rice noodles
Palm sugar
Coconut milk
Coconut cream
Whole white peppercorns
Green peppercorns (canned or in a jar, in brine)
Fresh limes
Jasmine rice
Buy products from Thailand. You can get the same things from Vietnam, the Philippines, China, etc. but there are differences, so try to get the Thai versions.
Fish sauce - buy the highest grade you can find. First pressing. Ingredients are anchovies and salt. Nothing else. No anchovy extract, no sugar, nada. If you can't find a good one, look for the Red Boat brand, which is probably more widely distributed.
Soy sauces... look for those made the traditional way. Read the ingredient lists.
I wouldn't buy any of the condiments from a regular grocery store, or even a place like whole foods. They sell crap and it's vastly more expensive than Asian grocery stores.
There are many kinds of dried shrimps, get the smallest ones and the next size up.
Coconut milk in a cardboard box is usually better than the kind in cans.
Produce that you'll also want to keep on hand: fresh garlic, shallots, onions, green onions, cilantro, ginger, galangal, tumeric, cilantro roots (if you can find them), kaffir limes and leaves, regular limes, bean sprouts, thai chilis. Thai shallots are smaller than the ones you're used to, so "one shallot" doesn't mean one, big honking shallot like you're used to. The limes they use are also a lot smaller than the Persian limes we have in our grocery stores.
I don't know where you live but there are probably Asian grocery stores in Columbia. If not, mail order is easy.

There's a lot of stuff on there that's much more in depth but she's going to get you started.
Have fun, any questions just ask.
