No worries Tina.
You're getting a new setup, just put it together and start your cycle. You can figure out what fish you want while it is cycling. It takes a while to cycle.
There's a decent amount of options in a 10g tank, read up on other posts about "10g stocking" and use google.
Keep us updated on your process, but try to control yourself and not buy more fish before the cycle is over. It is MUCH harder to do a Fish-in cycle than it is to do a fishless cycle. IF you decide to go buy fish, you'll be doing water changes every day, or even twice a day for 30+ days.
