As I understand it, most of the "neural" strength gains happen in the beginning of training, the first 3-9 months. After that it's mostly physical, actual changes to and growth of the muscle.
You can lose fat and gain muscle while on a calorie deficit if you are relatively high bodyfat - 25+% for men, 30+% for women. The extra fat does what extra fat is supposed to, act as a reserve in hard times - the caloric deficit is made up from drawing on your fat. This will get you down to the mid-teens (for men) or low twenties (for women) in bodyfat %; after that you must choose between cutting (lose fat, lose much less or maintain muscle) and bulking (gain muscle and fat both).
This is not very well-studied in the science side, but is the experience of many trainees. This was my experience, too. In January I was around 25% bodyfat, and I lost fat and gained muscle with weight training, some cardio and a caloric deficit. However, once I hit 14-16% bodyfat, the fat loss stopped and the strength more or less plateaued.
From the lifts in your sig, Kingace, I think it fair to say you are not a beginner anymore, and that your bodyfat is about as low as it can go simply by drawing on it to fuel your muscle growth. I think you're at the stage where you have to choose between cutting and bulking, and during a cutting stage you won't increase strength much.
However, take what I say in the context of my experience and qualifications as seen in my sig and journal. I mostly know about beginners, about the first year of trainign.
