Just a few tips and comments:
1.) Whey protein is by far one of the best supplements I've ever taken (and still occasionally use). You're not a big guy, so one shake per workout-day will probably suffice. I mix my Designer whey protein with about 32oz. of milk to make about a 60gr. protein shake, which, combined with pastas, lean meats, and other dairy products is plenty of protein for a guy like you for the "regeneration period" that your muscles need.
2.) Muscle Building + Cardio does not mix very well. While you're not damaging yourself in any way by it, the only problem with cardio is that it has a tendency to pull from your muscle growth. I.E., if you do so much cardio along with muscle building, that your body doesn't have enough energy (complex carbs) to sustain yourself, it will eat what it needs from your [b]protein supply[/b]...not good. To offset this, eat plenty of semolina noodles. Good ol' vermacelli pasta noodles at the grocery store will supply your body with enough carbohydrates both before AND after workout, and have a surprisingly large amount of protein per serving. A bowl of pasta with a bit of marinara and a protein shake to drink is my ULTIMATE power meal.
3.) For Biceps, a good way to get started is using the full bar (as opposed to barbels) and a bench with elbow supports (for the "dead weight" lifting exercise). Find sets/reps that work for you, and here's a hint: at the bottom of the lift, where your arms are just starting to lift the bar, lift a few inches and hold for just a couple of seconds, before you complete the repetition. This will add bicep muscle quickly, and develop some nice forearms as well.
For back, I use the Lattimus Bar (Lat Pulldown). Do 3 sets, pull behind your back to where the bar is touching your neck (or as low as you can go) and try to get around 10-15 reps in each set. Not only will this build your back, but you will also receive as a bonus gift a LOVELY set of trapezius (area between shoulder and neck) muscles. I'm only 200 pounds, but shoulders really add a "dominating" appearance to your figure.
If you need advice for chest exercises...go somewhere else. I can lat pulldown 200 pounds clean many times, but I can't even get close to benching my own weight!!! (One of the problems when you go to the gym alone: no spotter).
Just keep chuggin' down those shakes [:P]
