1)Does anyone have a good muscle building program that they recommend?

To gain muscle mass I suggest you focus your time on compound exercise like squat, deadlift, bench press, dips, pullup, stiff leg deadlift and clean and jerk.

These exercises are excellent to stimulate natural human growth hormone and testosterone in your body. Make sure to train to failure with 6 to 8 reps, do no more than 2 sets to failure. Train no more than 3 times per week.

In order for your muscle to grow they need rest, so make sure to sleep a minimum of 8 hours per night. Eat 1.5 to 2 grams of protein per pounds. Eat enough calories ( multiply your bodyweight by 17 at least... so if you are 200 lbs multiply by 17=3400 that's the minimum)

Drink lots of water like 8 to 10 glasses a day minimum(Muscle are made up of 66% water)

Simple formula for muscle building: train hard, eat lots of protein rich food with enough calories and rest, rest, rest.

2)Do I need Protein Supplements To Build Muscle Mass?

Protein supplements are not a absolute must to build muscle. You can get all the proteins you need in food like eggs, meat, fish, cheese and milk. Just try to consume at least 1 gram of protein per pound of bodyweight.

Try to eat enough calories comming from good quality food like oatmeal, veggies, sweet potatoes, fruits. Shoot for 17 times your bodyweight for the amount of calories you need daily.

Also, don't forget to train very hard and intense. Short workout of 45 minutes 3 time a week. Finally get al least 8 hours of sleep every night with a nap in the afternoon if you can.

3)Is 7,500 calories ok to gain muscle and can I eat 3 meals a day of a 1,000 calories?

7,500 calories is a lot. I understand your metabolism is fast but this is a lot of calories and the weight you will gain will probably be mostly fat.

In my opinion you don't need that much calories you just need to eat enough protein ( At least 1 gram per pound of bodyweight but 1.5 to 2 gram per pound is better for fast muscle gain).

If your job involve hard physical work, then yes you could eat 1,000 calories a meal but for 90% of the population this will just result in fat gain not muscle mass.

4)What is a good diet and exercise routine to help lose body fat but maintain muscle?

Interval training and compound exercises like deadlift, squat and clean and jerk are the best to help you lose fat and maintain muscle.

Interval training is great for losing fat fast and getting you in top shape. Compound exercises are fantastic for building muscle and for making you out of breath. Both training are excellent for raising your natural human growth hormones and testosterones level, which have a big impact on muscle building and fat loss.

As for food, you should eat good natural food like fish, meat, cheese, veggies and carb food like oatmeal, sweet potatoes and brown rice.
