www.Beersmith.com, they offer a free 21 day trial, you can formulate your own recipes, and play with IBU's as well as gravities. Like I said research the Late Extract Addition method, it will improve color (lighter beer due to less caramelization) and improve your hop utilization.
I have a 20qt pot that I will do a 3.5-4.0 gallon boil and I top off with PUR filtered water, I normally wash and sanitize my gallon water jugs a couple days before and place in the fridge to chill. When brew day arrives, I pour 1 gallon of the chilled water into the primary, add my cooled wort (same icebath method, usually around 100 degrees) and then top off with the additional gallon of chilled water until I get 5.25 or 5.50 gallons total. I will normally get my temps around 70-75, I pitch my yeast and there she goes.
As for recipes, search HBT for recipes there are a ton. If you like Stouts, I posted a recipe for one that turned out great it is under "my recipes" the key is to only add only 1# of the wheat DME to 3+ gallons of water along with the 60 min hop bittering addition, and add the rest of the DME at 15 min along with hops and yeast nutrient.
This forum blew my mind when I joined, I love it there is a ton of infor, and although it is probably already here somewhere, if you can't find it just post, most people are quick to respond and many have great info.
I am fairly new, but I have been quite successful so far, minus the dubbel I just checked the gravity on OG 1.078, at 14 days it is 1.026, that is only 66% attenuation, and this yeast is supposed to attenuate at 74%+, so I will be posting a question shortly.
Welcome to HBT, good luck, and happy brewing!
