PLANS: To plan or not to plan?

OK, so I have been putting off my build because I am afraid of screwing it up. I have good mechanical skills and residential construction experience, but I have never tackled a project this big (or one that means this much to me) by myself before. My HF trailer is all laid out in my shop but I haven't quite had the courage to drill the holes for the necessary changes to the frame. In other words, I am afraid to commit myself.
So... I think I need help. I have been considering buying a set of plans off the internet, but I don't know who to buy from or anything like that. I understand that my build will probably differ significantly from any set of plans that I use. But I think it would be comforting to have hard and sure data for all the little details that I get bogged down on, like axle placement and tongue weight and wall thickness and and and etc (all things I can find individually either here on the forum or elsewhere but that it would be really nice to have one place (and in the order I need it hopefully) so that I can ease my mind). the other difficulty is that I don't have internet at my shop and it is several miles from my home, so figuring things out is trickier.
What plans have all of you used? I am immensely impressed by those of you who are able to do this without plans, but I don't think I can go that route, at least not entirely. So I want to know what plans are good? What is a waste of money? I am sure there are those of you out there who have purchased multiple plans, so what was best? and why? The why is perhaps the most important to me, that way I can decide if your reasoning is the same as what I need. Free or inexpensive plans would be nice, but I am willing to pay a bit if it will help me.
I am interested in any type of plans that might be helpful, but for the record, I want to build a fairly traditional Teardrop or benroy, approx 5x9 or 5x10. I think the smaller tears are cuter, but I am over 6 and a half feet tall and need the extra space.
Thanks so much!
