The baby geckos you found could very well be Mediterranean geckos, but don't forget that the juvenile colouration of many geckos is different of that of adults. There are dozens of small geckos that may fit the description you gave. Maybe post a pic later to see if anyone on the board can ID them?
In any case, most of these small geckos have similar care. Most are nocturnal, so no additional lighting other than a heat bulb is necessary.
So that they are easy to monitor, you may want to consider housing them with paper towel as a substrate and a small potted plant or two to hide in. They should be fed pinhead crickets (very small crickets, literally the size of a pinhead, they can be bought at most pet shops) and dusted with a vitamin/mineral supplement daily (also available at pet shops, HerpCal is a good brand). Also, mist the enclosure twice daily with warm, dechlorinated water, most geckos don't drink from a bowl, but lap up water droplets from leaves and the sides of the enclosure.
To keep the enclosure warm (if you don't already live in a warm region) you could set up a 40 watt (or lower) incandescent bulb over the enclosure. Although a greater wattage, like 60, can be used to warm adults, I'd worry that a hotter bulb might dehydrate or fry the little guys during the day.
Here are a few links to some sites that may help you out:
http://www.geocities.com/RainForest/7917/medit_gecko.html (Meditteranean gecko caresheet, although I don't agree with some of the info on this page. I'm not sure about reversing the gecko's photoperiod, messing with the lizards' internal clocks may not be a good idea. Anyone have any input on this? And heat rocks are bad. Very very bad. Never use them.4 geckos for a 10 gallon tank is also cramped.)
http://www.gekkota.org/html/h__turcicus.html (Some more photos of Mediterranean geckos, are you sure this is what you have? This site has many great photos of tons of species, you might want to do some browsing to see if you can figure out what kind of geckos you have.)
http://www.anapsid.org (Great site on reptile care overall. Lots of info you can use.)
Hope this helps at least a bit.
