Dont be so anxious. As newbies we all are but you should let your beer age to get the full potential of brewing. Read the forum religiously and can you find many different strategies such as 1-2-3 and many others. You should ferment for at least 3 weeks in primary / secondary (optional) and at least 3 weeks in the bottles. My 3rd batch was 7 days old on Sunday and it is a brown ale as well and my gravity was 1.020 as well. I had 0 airlock activity throughout all of fermentation same as with batch #2 which was bottled on Sunday. Wait another week, take a gravity reading and see whats going on.
My other recommendation to you is to get another primary so you can do multiple batches. You will build up your pipeline in no time and be all set. I am currently planning my kegerator setup I guess I got the itch....
Old school or the new, doesnt mean a thing if your heart's not true!
