It's curious the names came blurry...since you use a word processing software, the only things you should be sure to print correctly are the words and letters
What fonts did you use ? bitmap or vector (opentyp, truetype, etc...) ?
For the software, take a look on Inkscape ! really great vector software
You'll find plenty of tutorials on internet, and even books in libraries.
For vectors graphics (logos for example) , you can find some here :

You can also use the vectorization tool in the software, to transform bitmap (pixels) in vector graphics. It works pretty well, especially in small scale.
TO make stripes, and stuff like that, you'll have to draw it by yourself on INkscape. You'll see, vector design can look difficult "out of box", but just do some simple tutorials on internet, and it will be fine !
Be aware also that there exists a scale limit of what you can do with a personal printer and decals sheet, especially with inkjet ones. But using proper decal sheet, good printer settings and vectors, you should obtain decent enough results.
