Hello Liam,
I'm gonna send you a few links on this post, 'cause you've asked a few big questions lol, but this is to a blog that I write, not a product.
To start with, I train beginners twice a week normally. They could do more but I find this is about right for most lads in terms of recovery and muscle gains.
I don't usually encourage the use of machines, free weights are better if you're prepared to take a little time to learn the movements.
Here are two posts with exercises that are very effective

Those articles are not instructional though. A good database for complete instructions is at www.bodybuilding.com. I highly encourage you to use these exercises, they are very good exercises.
In terms of foods for building muscle, it is important to note that no foods have magical properties but higher protein foods will be conducive to muscle gain. Here's a good list

Weight is lost easier through dieting generally, to find out how many calories you should be eating, here's a quick method for working out how much you need to be eating to lose weight.
Multiply your weight in pounds by 15, then subtract 500.
So as you're a little over 200lbs
200 x 15 = 3000kcal
3000 - 500 = 2500kcal
Eat 2500 calories each day and you'll lose 1lb each week, you'll want to recalculate this every month or so as your weight decreases.
Calories count, aim for high protein foods, get to grips with the exercises I've linked you to and you'll be well on your way to a better body.
All the best
Theo
