How to set up my file in Inkscape?

Here is a file set up checklist for Inkscape:
File is exported as an .eps;
All holes and cutouts are at least 50% material thickness;
File is built at a 1:1 scale, preferably in inch units;
All objects are on the same layer;
All stray points, duplicate lines, empty objects and text areas have been removed;
No shapes have open contours;
All shapes have been united, combined or merged;
All text has been converted to outlines or paths;
Cut-out text (reversed text) has bridges or has been stencilized;
