Sugar Gliders , what should I do ?

Okay , so I received 2 sugar gliders last Saturday . They are over one year old , so I am taking it slow with them . These gliders came to me from my cousin in a tiny little bird cage ! Their pouch was soiled with urine , &nd looked like it had mold growing on the back , she had toys crammed in the cage ( remember this is a little bird cage ) .. &nd the running wheel is also too small ! She also had them on HARTZ BONANZA hamster gerbil diet , &nd wasn't giving them anything recommended for sugar gliders . They do not come out unless the room is pitch black , &nd if i happen to walk in my room &nd turn on the light while they are out , they will stay out for like 3 minutes then run back into their little pouch . ( They won't let me put my bare fingers next to their pouch ) They don't come out again until the lights and the TV are off . They don't seem upset or anything .. I bought a new cage , wheel , toys , food , pouches , etc . I want to know when it would be the right time to take them out of the cage , because like i said , I got them last Saturday , I want them to be able to get out &nd excercise . I haven't handled them yet , because I want them to be comfortable with me . Also , they are both bitey ( not in an aggresive way .. but they are still biting really hard ) so should I wear gloves when I take them out ? They have tried to bite me multiple times , but never succeeded , &nd they have crabbed at me . They have bitten my mom though . I have done a ton of research , but I'm not really sure what to do in these situations .. Any suggestions ? Thanks .
