I love to brew RIS, but I would definitely not do that for your first brew. To brew one well takes practice and some equipment/ techniques that are not part of a beginner setup.
http://www.northernbrewer.com/learn/homebrewing-101/step-1/Start with something like that for info. If you think you'll get into it, read How to Brew. It's available online-
http://howtobrew.com/ but I think a copy of that belongs in any homebrewer's library. Once you get more into it, Radical Brewing is probably my favorite homebrew book. There are great ones about specific styles and techniques but I think Radical Brewing is a great blend of interesting facts and science, history, techniques and ingredient info.
If you are serious about brewing RIS, you should get equipment for and practice yeast starters. Temperature control is critical, so make sure you have a spot that stays constant and is in the low (preferable) or mid 60s. An oxygenation setup will be a benefit to you, but can be done without. To really do the style justice, you'll end up wanting to do it all-grain since the amount of extract needed will typically leave too many unfermented sugars behind and there are other grains you'll want to use.
The best styles for starting out are ambers, hoppy beers (they go great with extract), dry stouts and other middle gravity and slightly darker beers. Brown ales and Irish Reds are some of the most popular beginner beers. No matter how advanced your setup will be to start, you should absolutely practice with a few beginner beers before diving into higher gravity stuff. They are way cheaper and the whole routine takes practice.
