The list isn't long. It basically comes down to clippers, knife, glue. All the links below are affiliate links so I might get a little kickback from Amazon if you use them, but it won't cost you anything extra.
The clippers are used for separating parts from the sprue. They shouldn't be very large, and need to be of the style where the side with the cutting edge is flat, so you can get as close to the part as possible. You should be doing two cuts when you remove parts from the sprue. The first cut is on the vents, close to the sprue and away from the actual part you are trying to separate. Clippers put some force on the plastic, and if your first cut is too close to the part you could warp, stress, or otherwise damage the part. The second cut is to get most of the rest of the sprue off your part. You can spend twenty dollars or more on clippers, but a seven dollar set will suffice. The GodHand brand is widely viewed as the cadillac of clippers.
For a knife you don't need to be fancy. Your run of the mill X-Acto knife is going to work just fine. You'll use the knife for cleaning the last little bits of sprue off your parts, and also for scraping along any mold lines left over from the manufacturing process. Some people buy files or special tools just for removing mold lines, but I've been using an X-Acto blade for that purpose for decades and it's worked just fine.
Last up is glue. When you're working with plastic models you want plastic cement not super glue. Super glue will hold things together but is likely to break if it gets a hard jolt (like if you drop it). Plastic cement lightly melts the two plastic pieces and when it dries the two pieces have essentially become one. Plus it has the added benefit that it won't glue your fingers together. You do still have to be careful not to get it on parts of the model you don't want since it can melt fine details. Lately I've been using Citadel Plastic Glue (expensive) and ModelMaster Plastic Cement (cheaper but smells like weird bananas) and both seem to work equally well. Some people like Tamiya brand since the bottles come with a brush in the tip that makes getting the glue where you want it easier, and doesn't get clogged like the other bottles.
You'll need paints and brushes when you get to painting your models. Any search for model painting starter kit will find a host of possibilities. I don't have any direct experience with any of them, but be on the lookout for something with a couple brushes, colors that will work for what you're painting, and some kind of wash or shade color.
You could also just go the Contrast Paint route. Check out the below video for some enlightenment on what that entails.
