Help critique my "program"

Stats:
6'-0" 303 pounds, 36% body fat, sedentary career, was sedentary home life until I got this gym membership.

Diet:
My diet is pretty simple, this is pretty standard. I aim for 1,500 to 1,800 calories a day.
7a cottage cheese and fruit
9:30a egg white omelet and chicken sausage
Floating morning snack= fruit (mango, pineapple, strawberries, peach, cherries...whatever looks good at the farmers market that week)
11:30a grilled chicken and rice or veggie (or a salad, no dressing)
1:30p hummus and "rice and seed" tortilla chips (plan to swap the chips for veggies when the bag is gone)
5p grilled chicken & steamed veggies
I generally don't want anything else to eat after 5, but about once a week we go to the froyo place where i'll get ~8 oz of eurotart yogurt & fruit.

I'm drinking 16-20 cups of water a day, plus unsweetened tea or unsweetened green tea when i need flavor. If i want sweet i'll add a teaspoon of splenda to my tea.

Soda is all but cut out, I had one yesterday for the first time in a while. it tasted terrible. I also cut out alcohol. All of the above has been steady for over month now, and it's become EASY. There are days where I ***** because I'm full but need more calories.

I track all my food with MFP online and on my android. I started tracking my food intake without making any changes. slowly I swapped bad for good to get where I am now. I feel pretty confident that my diet is sustainable and reasonably healthy.
The slow transition period helped me immensely. I've "tried" to loose weight for all my life, this time around is the first time I feel like I'm making progress towards healthier living. I recommend the slow transition and food log to anyone who struggles with their weight.

Supplements:
BSN NOXplode caffine free pre-workout (could be placebo, but I feel I get a better work out with this stuff)
BSN LEAN DESSERT PROTEIN - post workout
one a day weight conscious multi-vitamin
I haven't been religious with that post workout protein, I may not replace it when it's gone to avoid the calories.


Last failure:
I can fill a lake with my excuses as to why last time didn't work out, but i think the biggest one is that I just didn't like the overcrowded tiny gym. So now I joined a big *kitten* LA fitness 3 weeks ago. I love the new gym, and look forward to going.

Currently:

I've been to the gym every weekday for the last 2 weeks, and a few days 3 weeks ago. A stomach virus prevented me from having a full week that first one, but each since has been full.
Every visit to the gym ends with me on a stationary bike. 30-40 minutes on level "10" out of "20". averaging a speed of 13 mph, heart rate between 130 and 150 according to the machine.
I'm starting SLOWLY with weight training. I'm using the same principal I did for my diet transition. I have been doing 2 sets of 8-12 reps. arms one day, legs another core/back another. I haven't got the workouts or starting routine in stone yet, but next week will be my first where I log everything. I know most people will frown on the way I'm starting the resistance training, but this method worked perfectly for my diet.

I had the "free" visit with the trainer at this place. It was a waste of 2 hours...yes, two hours. It was like talking to a used car salesman, he was more interested in negating all my research and getting me to sign up to an astronomically expensive program. I also had no confidence in his ability to work with someone in as terrible shape as I am in after the meeting.

My questions: Finally, enough background.

1. Why do people that prance around like boxers randomly punch themselves in the head?
2. How do you use a steam room and sauna? etiquette?
3. Do you have a decent resistance training log I can print and use?
4. Where do I find the cheapest supplements? is DPS the place to go?
5. I could use some links for information on strength training. I feel it's my weakest point knowledge wise right now.


I'm sure I'll have more, but I'll ask them as they come up.
