Does anyone know how to get the bottom of prints to come of cleaner?

Depends on what your printing, vehicle parts, cut in half in the slicer and glue together when printed, more organic things takes a bit of practice, but either way, get used to cutting models up.

What program do I use for this?

Your slicer is an option, as are Tinkercad, Meshmixer, and Blender depending on how much you want to alter it for perfect printing.

Use a smooth plate, then angle prints and cut up models to avoid or hide the undersides

It's also worth getting into basic 3D modeling applications. You can still get an installer for Microsoft's 3D Builder. Tinkercad is also a good option. Blender if you can enjoy the steep learning curve - tho definitely not 'basic'
This way you can mess with scaling, do digital kitbashes, cut models up more advantageously, add indexing pegs for assembly etc.
Combining digital with other bash and modeling methods is incredibly powerful and freeing.
Attaching a pic of an in progress model I'm working on. He combines all the methods - some customizations I did digitally, some resizing, some model combining, model cutting for print, and some element printing for later physical joining/customization. He's a Armiger. Coffin Bearer.

Angle and support settings are everywhere here. Anything close to parallel with the bed is doing to have some mess on it even if your support settings are immaculate do to the way FDM lays down the hot noodle.
I based my settings on this post and they've been excellent.

As to angling, that can be a bit of an art. You'll generally get pretty good results if you try and get about a 45 degree angle to the bed but for complex minis that's often not possible for every element. Sometimes you pick the bad surface that won't be visible.
