Congrats on your new furry friend! Congratulations!
Unfortunately, a lot of that stuff won't do you any good. Pet stores, in general, seem to dish out a lot of bad advice, so do a lot of reading here. There is so much good info to steer you in the right direction.
Chinnies like to chew, and fleece is the safest fabric for them. So ideally, your hammock should be made of fleece.
No fruit or veggie or sugary type treats. Their guts can't handle the sugars. Chins don't need treats anyway, but if you do want to give the occasional treat, go for plain cheerios, plain shredded wheat, rosehips, oats...wood chews, such as (prepared) apple sticks and hay can be given unlimited.
A flying saucer or chin spin is a safer option wheel.
A good pellet is a must - mazuri and oxbow are a couple of examples.
And make sure you have plenty of fun with your baby, but give her time to settle in. A new environment can be a bit stressful and it takes time for some to get comfortably settled in.
Have fun!!!
