Breaking this into two parts.
1. Veiled chameleon, female, 2 months old. I’ve had her for two ish weeks.
Are you certain she’s a she? Males will have protruding little nubs on their back feet called tarsal spurs. If in doubt, post a clear pic of her back heels. I think she looks maybe a little older than 2 months, but only by maybe a month or so. I’ll base my suggestions on an age of 3 months.
2. I only handle her when needed cause I know it can be stressful especially since she’s in a new environment
Yes! You will want to start working on building trust with her. While she may never be ‘friendly’ and come out onto your hand on her own, trust is still important. This is a great blog to go by. https://www.chameleonforums.com/blogs/building-trust-with-your-chameleon.2396/
3. I feed her live crickets, usually at least 3 a day, one in the morning and two in the evening.
Variety is always best and at her age, she needs to be fed much much more than that. Many on line vendors sell species specific variety packs, which are great if you have only 1-2 insect eaters. Do check the forum sponsors and the graphics below. https://www.chameleonforums.com/sponsors/?tag=food For her age, she should be getting at least 15-20 appropriately sized feeders once a day in the morning. For size, anything larger than the space between her eyes is too big. My personal preference is to feed a bit smaller and just give a little extra. It’s also very important that the insects be as healthy and well fed as possible, so that they are more nutritious. You don’t need to specifically gutload, but instead just keep your bugs well fed. The orange cubes, jelly pots and most of those things are very poor for nutrition. I feed my bugs a variety of fresh veggies, greens and a little fruit plus the occasional bit of Repashy Bug Burger.
4. I use Reptivite vitamins with D2, I put them on my crickets every time I feed them to my chameleon.
Reptivite with D3 is a great multivitamin and D3 combo product, but is to be used only one feeding every other week. It contains preformed vitamin A and D3, both of which are fat soluble (meaning not excreted quickly) and can quickly build up to toxic levels. Stop using this for at least 3-4 weeks. Use only a phosphorus free calcium without D3 lightly dusted on every feeding. You’ll continue to use this for every feeding except when using the ReptiVite with D3. Repashy Supercal nod is a good one. https://www.amazon.com/Repashy-SuperCal-NoD-Oz-JAR/dp/B00N3BKCGA?th=1
5. I have an automatic misting system, it goes off every hour for 45 seconds. I also have a little fountain that gives the sense of a natural water source, I see her drink from that the most.
You need to adjust your mister to mist for longer (2 minutes at least if able) and less frequently. The ideal is for right before lights go on and off. If needed, you can add a brief 1 minute misting mid day or use a dripper if so inclined for about 15-20 minutes. It’s important to let the enclosure dry out during the day. If your night time temps are consistently below at least 68, you can and should use a fogger/humidifier for a few hours in the late night/early morning to simulate the natural hydration they get from fog in the wild.
6. Her droppings are a tan-ish color or a brown, yes she has been tested
It’s always a good idea to have a fecal and general wellness visit. Gives a chance to meet your vet too and hopefully you’ll never need to see him/her again. 
7. Additional info is that she was not fed very well when I bought her, her ribs were very visible. Since I’ve gotten her, she has thickened up a lot and now you can only see a little shadow of the ribs.
Where did you get her from? Most pet stores have substandard care and little knowledge of chameleons and the sources for getting their veileds is usually questionable.
Unfortunately, there are no specific breeders of veileds in the US as it isn’t a profitable business. The closest trusted source I’m aware of is Fram’s Chams, who occasionally breeds veileds. Most usually come from reptile ‘mills’, farmed or wild caught from Florida or ‘backyard’ breeders.
