^ very good advice. I use BrewSmith, which is available for download and even has a free trial period before you have to buy the key. It will help by making complex calculations for you. Once you have a couple batches under your belt and know your efficiency then it will be even more accurate.
I can't sound the "K-I-S-S" gong enough. When I see recipes with a confusing number of grains and as many different hops it makes my butt pucker. Sometimes these ingredients actually do the opposite of what they would want for the beer--like adding flaked barley to a beer that is supposed to settle clear.
Also, resist the biggest disease to strike new homebrewers. It's the "if a little is good, more must be better" mentality. I don't mean batch size with this, but the amount of an ingredient used. Somethings that are great in small amounts, a large amount of it might just make something that even your toilet won't want to swallow.
Finally, learn the basics of beer and of your ingredients. People have been brewing beer for thousands of years and the ancients seem to have been pretty good at it. Some things always work; some things work under certain conditions; some things never work--and likely never will. This isn't meant to squelch your creativity, but learn the rules and why they are there, then you can start breaking them. The best and most creative musicians study the theory (rules) of music. This teaches them what will and will not work so they can be creative within this framework. While they appear to be breaking all the rules they are actually just stretching them to their very limits.The same goes for brewing. Some things will always taste bad no matter how many times people try them. Learn these and then express your creativity within this framework. If you think you are going to totally reinvent brewing, you won't. If you waste a lot of time and money on ingredients or recipes that would gag a goat you will only get discouraged. This is homebrewing so feel free to break the rules, but you have to know them first.
