The parent poster has a lot of good advice. He has said a lot of the same things I would say, only better.
One thing I'd like to point out is that the books you're looking at might not be as useless as you might think. The specific examples in them might not apply to you, but the general principles probably do. What I mean is that the sports jockey who neglects his wife to follow his favorite sports/teams is not all that different than the gamer who neglects his wife to make it to that raid in WoW (just an example, if you don't play WoW, then apply it to whatever games you do play).
I'll use myself as an example: my wife thinks I play too much WoW. I don't play as much as I would like to, but I've reached a compromise with her: she allows me to raid 2 nights a week. I choose the nights, but I have to let her know in advance (at least 24 hours if possible). I've found a good guild that works with me on that, not the best but far from the worst, and it's allowed me to see most of Ulduar (up until yesterday the final raid instance in the game). If she sincerely asks me to, I would drop WoW in a heartbeat, but I don't think she ever will as long as I keep it in moderation. She knows that WoW is something that I enjoy, so she lets me play.
I have to second what the parent poster said about putting your wife first. The best, most happy and fulfilling marriages are those in which both partners do this. You can't control whether your wife does, but you certainly can control whether you do! And when you do, your wife will most likely reciprocate. Don't try to keep tabs, though - the geek side of you might be tempted to try "keeping score", but that is not healthy. Just serve your wife and let her (but don't force her) serve you.
Definately do things together. My wife and I are similiar in some ways to the relationship described in the article - she likes to read and I am a gamer. So sometimes we read together (we're working through Robert Jordan's Wheel of Time together, I've read it before but she hasn't), and I've actually gotten her to play some WoW (she's nowhere near as interested in it as I am, but she enjoys playing it together with me).
Don't listen to those who are telling you not to get married. Marriage to the right person is a wonderful thing, and you will have many years of happiness if you do it right. Yes, some marriages end in bitterness, but the best way to avoid that is to marry the right person in the first place, and then continue to treat her in the marriage the way you did while you were dating. The time to figure out if it's not going to work is before you tie the knot - if there are any significant issues make sure they are dealt with as getting married won't make them magically disappear. But also keep in mind that there will be issues - no two people get along perfectly. There's a saying that you should date with both eyes wide open, but keep one eye closed when you are married. What that means is that once you are married, don't dwell on your wife's faults. She isn't perfect, even if she might seem that way now. You will find faults in her, and her in you (possibly even some that you may not yet be aware of or even think of as "faults"). But don't use those faults against her, especially as leverage when you argue. That is bad. When the stress of daily life is getting you down and all you can think about is what is wrong, take a step back and remember the good things about her that drew you to her in the first place. In truth, part of the joy in marriage is working through disagreements because in the end, having a happy wife is worth all the trouble.
As a final thought, in case you're wondering, I am happily married for coming up on two years (my second anniversary [don't forget your anniversary date, she won't] is in less than a week). I look forward to many more years of marriage. Good luck in yours, and may you two find happiness together.
