Let me slow you down a bit, if I can.
I don't believe new brewers should be fooling with recipe development until they have mastered the process of brewing. In fact, unless you have an experienced brewer helping you, I believe you should use a kit for the first few times while you figure out the process.
Brewing isn't rocket science, but neither is it simplistic. There are a lot of moving parts, and it takes a bit to figure them all out.
Further, if your beer doesn't turn out, what will you identify as the cause? The recipe? The process? No way to disentangle those things, more than likely
In my opinion, you should brew a simple kit the first time or 3, and get the process down. When you're able to produce what the kit intended, then consider going to more involved recipes and even starting to do your own. In fact, I don't think newbies should be doing all-grain for their first few times, as it complicates the process even more. Doing a few extract kits would reward you.
To me, the key is to ask yourself where you want to be in six months, not in 3 weeks. You're not going to be brewing world-class beer in 3 weeks but if you use a relatively simple recipe and focus on learning the process, you might be closing in on that world-class goal in a year or so.
My 2 cents. Either way, welcome and good luck!

I taught a buddy to brew all grain, but he learned it under a fairly controlled set of conditions. The first time, I made all the decisions as to recipe, water amendments, mash temps, boil, hop additions--everything. He watched me brew that first recipe; I explained what I was doing and why, he asked questions, and that beer was great. To his great credit, he decided to pursue a learning agenda, focusing on where he wanted to be as a brewer in six months, and not forcing the issue.
The second time, he did everything while I watched and kibbitzed. I still made the decisions for him, but he did all the physical things, and he had to be corrected a few times. That beer also turned out great.
The third time he brewed I wasn't there. I still made the decisions (approved recipe, told him water amendments, discussed timing and mash temp with him), but he did all the process on his own. I got about 5 texts and 1 phone call during the brew day, but he made it through, and that beer also turned out great.
IMO, you *can* get up to speed in a hurry, but only under the right conditions. If you want your learning curve accelerated (and who doesn't?), focus initially as much as you can on the learning and less on the creating.
