In fact, some home printers now function as copiers, so with the right hardware, you wouldn’t even have to leave for the office supply place.

As to your questions: I basically just pulled the pages out. You could certainly use an X-acto knife, and you’d probably get somewhat more even results than I got. However, I found that, if you work on pulling out an entire adventure at a time rather than going page-by-page, it’s both fast and pretty neat. You actually wind up dislodging the pages from their binding in most cases, rather than actually ripping them. The problem of multiple articles sharing the front and back of the same page (if I’m understanding your question correctly) is a somewhat sticker wickett, though. When I could, I just made the adventures back to back. Honestly, though, I didn’t run into the problem all that often. Dungeon, at least, has enough ads that that particular issue doesn’t occur that often, or if it does you’re only really losing the full-page leading artwork, rather than the text of the adventure. A fair price for convenience and efficiency, in my opinion.

I actually think that this process is going to be easier with Dragon, even though I have about a metric ton of the magazines. See, a lot of the articles in Dragon are loads of fun to read, but aren’t imminently usable in the kinds of campaigns I tend to run. As such, once I’ve read them I have no more use for them, other than maybe sentimental value. I’ll probably use things like feats, spells, monsters, items, and maybe the occasional prestige class, but the monstrous ecology articles, and the articles on elven life, and all that kind of stuff is stuff that I’m not that broken up about parting with. Like I said, they were good reads, but I’d just as soon come up with that stuff myself in my own campaigns.
