Your resistance training to cardio ratio is off; 6 hours a week compared to maybe 1 or 2 hours tops of resistance training is a joke.
There's no hard and fast rule on it, but you should aim to get at least two 1 hour sessions in per week, if not 3 i.e. at least 2 hours of resistance training per week. Cardio needn't take hours either, if you started doing HIIT which is far less mentally tiresome, more effective, enjoyable, and generally more awesome.
Resistance training is not something you can tack on to the end of your workout for 15 minutes. Do it properly, or don't do it. For energy and performance's sake, you're best off doing your cardio separate from your resistance training i.e. have separate resistance training sessions.
You get out what you put in - freeweights are harder, but yield better results.
Read the stickies, everything you could want to know is in there, specifically Powerlifter's thread on "getting toned" for the ladies. In order to improve muscle definition ("get more toned"), you need to decrease your bodyfat % level, and maintain what muscle mass you currently have, if not slowly aim to increase your lean muscle mass over the next couple of years (a slow and arduous process for women).
On a positive note though, good job on cutting down on the alcohol - that stuff is poison
