Putting subroutines first was important back in the days when compilers were less advanced. So you declared a bunch of routines at the top of the file, and then at the end of your file you had the main routine that called them all.
These days, that's not necessary. From a style point of view (he said, donning his asbestos firesuit), I like having the 'main' part of the routine first, so that at a quick glance of the file, I can see what's going on. If I want further detail, I can scroll down to look at the routines I'm interested in.
And to address the use of '&', the short answer is Don't Use It. The long answer is, Use It If You Understand What It's Doing And You Actually Really Do Need That Behaviour.
