Yes, the better one is better, especially when you want to move to AB or other plastic types. Some people like to print on glass. I use aluminum bed at 60 C coated with glue stick glue. Glass with hair spray works and blue painters tape. Everyone developes their own prefferce.
As for software... You really need some 3D CAD software or else you can only print things others have made. Not a bad why to start. but you eventually want to peint your own designs. I like Fusion 360. Others like other things. But one thig abut Fusion s that it can drive a milling machine or lathe. You can print of mill the same 3D model. Fusion will figure out tool paths as well as save to files that can be printed. So you either download an STL file from Thiniverse or make a STL file using fusion360 (or sketchup or freecad or...) Then you run a slicer app. I like Cura but others will like "Slic3r". Both are open source. Both accept an STL and then you set 100 parameters and they creat g-code. Don't even bother to look at the g-code. It might have literally one million lines of code and control 4 axis, 2 heaters and some fans You can expect about 3 weeks of frustration because nothing will work, then it will. After a while you start thinging about parts design diferently because now 3D compound curves with an organicshape are easy to make. Think of a cordless drill case with an external round shape and interior made to hold al the parts. that ould be way-hold to make on a mill bu is a good student project using fusion and a printer.
