Monte's Log, Featuring a Debate About Dotard Genetic Potential with an Ant

Brief Background
Long time lurker who recently registered. I'm 31 years old, 6'4", and 220 pounds. When I graduated college 10 years ago, I was the same height, but weighed 165 pounds. After college, I found the gym and packed on a lot of muscle over the subsequent 2 year period of working out, but did the typical broish bench/curl-centric exercise routine while rarely squatting or deadlifting (i.e. I maxed out at 330 benching and 235 squatting). Since then, I've periodically gotten back in the gym for six months or a year at a time, but never consistently.

Recent Workouts
Recently I've been doing 3 sets of 40 pushups and a total of ~25 pullups 4-5 times a week, and also playing squash a few times a week. Since beginning squash (which is very high impact), I've been having periodic weakness/pain in my right knee, but other than that no issues except chronically tight hamstrings.

My Plan
This is yet another starting SS log; I'll be doing the version with pullups/chinups and without PCs (at least to start), but I will be deadlifting for the first two weeks or so until my gains start to level off. I've read the book and the wiki, and I'll be starting on Monday. I've purchased the appropriate lifting shoes and chalk, and I'll be doing foam rolling on my problem areas post-workout. I also plan to purchase Assess and Correct or something similar shortly in order to work on my flexibility issues.

My diet is pretty decent, with a lot of skim milk/oatmeal/protein bars/lean meats/veggies on my good days (at work), with the occasional pizza and beer meal thrown in (usually weekend). I haven't been doing daily tracking, but I plugged in an average day and I'm around 2800-3000 calories with around 150 grams of protein a day.

My Goals
This log is mostly for motivation. I'm not entirely sure but I would guess my body fat percentage is somewhere between 20 and 25%, so I guess I'm shooting for recomposition. I don't have many specific goals in mind. My main goal is to get stronger, especially in my lower body (maybe get my combined deadlift+squat+bench to 1000 lbs). I'd also like to tighten up my midsection and lose the 15 or so pounds of extra weight I'd guess I'm carrying around my gut.

Questions
-I'm assuming I should up my protein intake? I'm not really sure what my LBM is exactly, but if I use the 1.5 g/lb LBM I should up the protein to between 225 and 250 g/day, correct? I can throw a scoop or two of protein powder into my morning and evening skim milk if necessary.

-I'll be lifting at lunch with a coworker; this is the first time I haven't worked out in late afternoon. I am used to having a post workout recovery shake (e.g. Endurox) and then eating my largest meal of the day 1-1.5 hours post-workout. Should that still be the case if I'm working out at lunch -- that is, should my lunch be dinner sized, and should my dinner portion be smaller?

-Any tips or suggestions from other tall guys, or people who've trained with tall guys, about pitfalls or things to avoid involving squatting would be welcome. I suspect the answer is "shut up and lift weight" but just thought I'd ask.

Thanks in advance!
