This will be a personal matter, depending on whether it will be helpful for finishing or sharpening. However, it is a good idea to look beyond your current use of this space to the next owner. Would it be beneficial to add plumbing hookups so that the shop could someday be an apartment, or an art studio, or an extension to your house? It could add to the resale value of your house to be able to create as flexible an area as possible by roughing in a bathroom and even a kitchenette area if you can. If this is done when wall cavities are open or before the slab is poured, your forethought could pay dividends but not cost much up front.
I looked around at many versions of Taiwanese drill presses. I ended up purchasing the Ridgid DP15501 15" drill press because I liked the way the quill stop was made, the work light, key storage, and the easy access to the belt change system. This machine was also on sale when I needed it, so that made it a slam dunk. Choose the one that suits you, as they’re all very similar. The table is large enough, and the distance to the column is large enough to allow you to do most anything a small shop needs.
Spray gun: Not every woodworking job gets a film finish, but most of mine do. And of those, everyone will meet a spray gun. For a million reasons, including making finishing fast and fun, I recommend using a spray gun whenever possible. It will raise your game and make you n0t hate finishing.

One of the challenges we all face is how to move machines into a home without damaging the home, the machinery, or yourself. I actually had to bring things through the front door, and across hardwood floors, and turn 90° to descend the stairs into the shop. To protect the floors, I laid down sheets of 1/2" MDF that I could use later. On the wooden stairs, I used three strips of softwood strapping, held with wood screws to the stairs. I mounted a 2x4 baton to the wall studs at the top of the stairs, with a 5/16-inch eye-bolt through it.
High-velocity fans are also an important tool in their own right, particularly at your finishing station. Increased air flow will help dissipate fumes from paints and sprays for your safety, and you can train a fan on your project to help paint dry more quickly between coats on humid days. To get the most out of your fan, look for floor fans that are easy to aim or wall-mounted fans that will save space in smaller shops.
As the comic George Carlin might say, a shop is mostly just “a place to put your stuff.” The physical aspect of a shop is indeed simply a space of some kind — a garage, a barn, a teepee — that keeps the rain, rust, and robbers away and houses a collection of implements needed to saw, plane, slice, sand, and pound raw wood into useful objects. But just like the difference between a house and a home, what transforms a building full of tools into a comfortable workshop goes beyond the mere physical aspect.
