Want to get into great shape, please help!

*Lees*

I really want to get serious with my diet, loose more weight, build muscle and basically get into the best shape of my life!!
I am 25, weigh about 10 stone and I'm around 5'3"! I lost some weight over the last few months but haven't really been consistant if I'm being totally honest! I have been reduced to a 3 day week at work and have just come out of a long term relationship so I am really determined to get into shape now that I have the free time especially!:)

I had a really bad week last week, I was eating crap and felt really rundown and I didn't get to workout much and I honestly feel like crap now and can see I have actually put on weight so I'm a little disapointed in myself but it gives me motivation and I know I need to stick with it if I want to see good results!! I started taking a multi vitiman also so hopefully I won't feel so rundown in future!
My diet prior to now was ok, well my intentions were great but I have been eating too much bread, potatos and snacking on junk that was in the house!! So, that's all going and I'm really determined to do this!!
I would really love some critique on my diet and routine, so any help would be greatly appreciated!!

Here's what I plan on eating...

Breakfast - Poridge 40grams made with water with honey/ omelette with bacon, mushrooms, tomato, onion
Lunch - Homemade vegetable soup with breast chicken/ breast chicken with salad/tuna with salad
Dinner - Chicken/Beef/Pork with veg (no potato)
Snacks - fruit or nuts

Here's my workout routine - (I got the weights routine from a site that was posted on here a while back but did change a few things around)
I do the weights routines in the gym before work, I finish my workout at about 8am but don't get to work untill 9:30 so I have been taking a protein shake after workout. I got a tub of BSN Syntha 6, it's almost finished and I do plan on changing it to get something with less carb content as I have been reading it's not the best for fat loss! (any recommendations here appreciated also!)

Mondays- 8 to 10 reps of each on 1st week, 15 - 20 on 2nd week and on third week revert back to 8 - 10 reps but drop set on last set.
