Ok.. I'll give you my basic tips, and you can always PM or IM me with any questions... I'm more likely to answer quickly if ya send me a PM or email...
An aquarium, with at least 10 gallons for 2 gerbils. The general rule of thumb is 5 gallons per gerbil, but they surely enjoy more room. I would recommend for a beginner to keep 2 gerbils in a 20 gallon long. The tank isn't too large, but it gives them plenty of room. (I love my 20 gallon longs
Aspen or recycled paper, like carefresh.. I don't like the paper beddings since I've had a few gerbils develop allergies to them, and they can be dusty when gerbils burrow.
Gerbils love running wheels, personally I love the mesh ones and have had no issues with them in the past 4 years I've used them. They can be oiled easily with vegetable oil or baby oil on the axel to prevent squeaking.. A gerbil's favorite toy/activity would be cardboard to chew. I recommend tp tubes and paper towel tubes, and if you leave a little bit of tp on the roll, they'll use it to make a nice warm nest (never buy that store bought fluffy nest material, it's deadly).
Gerbils aren't the MOST cuddly pets, but to them, they enjoy interaction with humans as well as other cagemates. To them, we make a good playground to crawl on and explore. I like to let my gerbils run around on my bed or sofa or in the bathtub (easiest cleanup for accidents). I have used playpens before, but the shorter ones have often been leaped out of... Gerbils are curious and love to run around and investigate, that's what makes them so endearing and easy to tame, also the fact that they rarely bite is a big plus...

For treats I like to give mine dried blueberries, strawberries, sunflower seeds, pineapple, banana chips, and organic cereals like kashi...
