It's fine. In the Prepare view red means that an area needs support. In the Preview red indicates "Outer Wall" extrusions.
I think it will come out much cleaner if you print it vertically. It will be stronger if you print it laying down.
Use a pair of needlenose pliers to crush the shell of the support. Just keep working at it. An option I've been using lately is to lower the Support Flow and Support Interface Flow to 90% (the settings are in the Material section).
Solidworks, Inventor, and Fusion360 are very good at creating good STL's from parametric models. Blender, TinkerCad, and some others need to be watched or the STL files will have errors.
Here is a Cura Project File. My Ender 3 Pro is the printer. I don't know your printer but when you open a Project File you will be prompted to Install a new printer, or if you happen to have an Ender 3 Pro the prompt will be to "Update" the printer. If you "Update" then your printer would end up with my StartUp and Ending Gcode so "Install New". Then you can slice it and see how I've butchered it what I've done.
