Just like any other quality in the body recovery can be trained for and enhanced. If you increase the number of weekly sessions you will most likely have to work through some soreness to adjust to the new frequency.
To enhance recovery you could eat the same number of meals every day or get an exact number of hours of sleep every day. Example: You always have three square meals and a protein shake almost every day and you always go to bed at 11pm and set the alarm to wake you at 8 in the morning. The body enjoys consistency above many things.
Another great way is to employ active recovery such as one outlined in Waterbury's 100 reps article.
And last but not least is ice massage which you can also look up in this sites new and improved search engine.
You're right, training and nutrition are given way more attention than recovery. But there's lots of great info non the less.
Hope it helps.
