Jason,
Here's a quick ref on glutamine - http://www.wholehealthmd.com/refshelf/substances_view/1,1525,10030,00.html
I just resumed a more serious weight training program, and I am currently researching protein powders. A friend recommended Myoplex, which does contain glutamine, but it is balanced with other amino acids. One also needs to check ingredients if one has food allergies.
EAS - Myoplex Deluxe or Original Powders.

As for creatine - a good source of information (I never used it - see below)

===================
Here is a good discussion of "weight training", as opposed to body-building.
http://exercise.about.com/cs/exerciseworkouts/a/weight101.htm
===================
I did weight training, in addition to working heavy labor (iron work) in my early 20s. At my peak, I benchpressed 275-300 lbs (125-136 kgs), and did military press of 240 lbs (110 kgs), both with bar in front of chest and behind head during resting. However, my muscles were not bulky - my weight was only 175-180 lbs (79-82 kgs) - and I could touch my finger and hands to the shoulders (same side and across). Here it is important to stretch.
Also, I ran long distance (at least 3 miles (5 km) each day - four or five days a week), rode a bicycle, and stretched all muscle groups. I occasionally played soccer.
As for supplements, I used a protein power supplement (can't remember which) that had a balance of amino acids. I made a milk shake - milk, vanilla or chocolate ice cream, baby formula (e.g. Similac), and protein powder. I never used creatine, and I certainly did not take steroids.
Baby Formula - Similac Advance, Similac 2 Advance, Similac Isomil - read ingredients.
If at all possible, swimming is a great low impact exercise for the arms, chest, legs and abdomen. In addition, the arms get full range of motion with crawl and backstroke.
====================
Also, take care of your joints, especially hip, knee and shoulder. As one gets older, injury or damage to these joints can be problematic. Once you get much beyond 40 yrs of age, healing takes much longer.
There are some who recommend "glucosamine and chondroitin sulfate" for joints. I still have to research these.
