How long were you previously going to the gym for? Stronglifts is definitely enough to get your your newbie gains while also learning the technique for the compound lifts. Also, depending on how active you are outside the gym, 2,600 kcals may not be enough, especially if you walk a lot or do other sports. Easiest way to tell is to track your weight over a period of time and see if it's going up or not. If it hasn't moved in a couple of weeks, add in an additional 200 - 300 kcals per day.
As for hypertrophy, I always found the boring but big template for 5/3/1 to work well for me. However, if you've been out of the gym for a while, I'd still recommend you run a linear progression program again such as stronglifts or starting strength until you stall, and then switch to hypertrophy focused training. This way you'll be able to use more weight for your rep work and get a better stimulus.
Definitely do reintroduce deadlifts when you can. Anterior pelvic tilt is caused by tight hip flexors, caused by a weak posterior chain, usually caused by generally being weak all over. Deadlifts will make your posterior chain strong and contribute towards the long term solution. To be honest, getting strong fixes a lot of musculoskeletal problems.
