There are commercially available turtle eye drops at places like Petco/PetSmart. You can try these as well. Carrots are excellent for eye health (high vitamin A), so you can see if the little one would like some carrot slivers. If you peel a carrot into long, thin strips, it kind of resembles a worm and most turtles eventually love carrots.
Another thing is to get the turtle eating. Baby Reptomin is good if you can get him/her to eat pellets. Otherwise, try a stinky food, like tuna (I recommend tuna from the pouch, not the can, makes less of a mess), just don't overdo it. Turtles will figure out what's the good stuff and what's not, and it can lead to feeding problems later on.
Read everything you can on this site, and I mean literally everything. Search the forums, and just learn all you can. It's the first big step you should take. The next step is getting the correct habitat.
Oh, and you should probably just pick a gender, whichever you prefer, give the turtle a name (which can be unisex if you'd like). My little boy Mikey turned into quite a large girl when she was of age, so I just changed her name to Umi to help the transition, and started using female terms. Some members of the board get a little huffy if you call your turtle it ...
