Everyone does it differently and you have to choose your own style. If there's a "Vista64" way, I do not know about it.
I have a bookmark folder for Vista Forums and it contains most links I've found useful (some are even threads or specific posts in threads) - both Tutorials from here and links from elsewhere on the web. I should probably take the time to separate the Tutorials, but haven't done so yet.
You could always create a "Tutorials" folder in your favorites list (or within a broader "Vista Forums" folder) and add to it anytime you find a link or tutorial that you think will be useful to you in answering questions. You can do this by checking the posts of those of us who reply frequently as they will contain the most frequently recommended (and then just add that link to your bookmarks folder) or you can go through the tutorials yourself and if you find any you think might come in particularly handy, include them as well. You may even want to break "Tutorials" down into 'Frequent Tutorials" and "Useful Tutorials" or whatever. Just don't go too overboard or you'll end up with a list that's so long it no longer serves the original purpose of making the ones you expect to use most often easier to find. At this point, I have so many, it's sometimes easier to just Bing the topic to find the link than to search through the list. I suppose I could do some better organizing, but I never seem to find the time for that. I probably should have started with several folders to separate the topics better - but alas, I didn't think about that until it was too late. If you prefer a document with the list as opposed to favorite bookmarks, that's up to you - whatever you feel will work best how you do things.
I also keep a Word document open that contains answers I've created and used in the past that can be handy starting points for future answers on similar topics. It's about 50 pages long right now. It's not well organized and I find things mostly because I use it enough to know about where everything is - and is another thing that could use some structure. Plus this document requires constant revision as new products become available, new or better links are identified (or old ones are removed), better ways to word things are discovered when editing the copied drafts (they almost always need some type of editing, but still save time) and the new post is then copied and used to replace the old one in the Word document, and new posts are created which deserve to be added as I feel they may come in handy again (especially if they involve a lot of research with a lot of links that I don't then need to do all over again). I think others do this to some degree, though I suspect few do it as much as I have. Whether or not you do something similar is entirely up to you.
I hope this helps.
