I consider the 75-300 to be the worst lens you can buy. I really think you should get the 100mm f/2.8 macro. There is no stepping stone. If you have to save up for 6 months before you get it, then so be it. Don't settle for less, because whatever you settle for can't compare. If you buy a 75-300, it will not help you practice for a 100mm f/2.8 and it will not give good results of closeups.
Just play with your 18-55 and learn how to use it well. Learn all about exposure and framing and lighting and all of the other things that apply to every lens. After a few months you should be able to learn how to use your camera and your 18-55 pretty well. Once you can afford the 100mm, I suggest you put on your speed belt.
