I have use Premiere Pro and I bought a kit so I have the tripod and stuff. I will be shooting and exporting in 4K. Im currently saving up for a Razer Blade laptop as well.
If you're using premiere pro and are going to be working with 4K footage you're going to need a monster computer.
Premiere pro is great but it's a huge resource hog. Get an SSD, the best processor, and as much RAM as you can afford. Don't go cheap or you'll regret it. One thing you don't want is for your creativity to be destroyed by having to fumble with a weak system.
For the camera, I recommend getting a gimbal. I use a Zhiyun Crane 3 and also own a Crane 2 and Crane Plus.
Lenses, I would go with the 35mm equivalent of: 50mm, 16mm, and 50-100mm.
If you have the money, get a metabones speed booster so you can use canon glass. If you do, the Sigma 16-35mm and Sigma 50-100mm art lenses are must haves. You'll need to get good with manual focus quickly though. Speedboosters do not have good autofocus at all.
Take lighting seriously; this is something a lot of people ignore early on. If you can get a 3 point Aperture system go for it. It'll be a long lasting investment and it'll take your production to a high level most indie people don't think of. Also, keep audio in mind as well. If you are going to be capture audio, then I recommend the Rode NTG3.
Some of these recommendations are very expensive but that's why I asked you what your budget was. There are plenty of options but without knowing your budget it's hard to be of any real help.
