A Good Weight-Loss/Management Routine?

So one of my New Year's resolutions was to start losing weight (my goal is to weigh 180 by the time I graduate) so I've been making a weight-loss routine (pieced together from other times I've started a routine, but fell out of it due to family issues or being unable to obtain transportation).

The routine I have is this:
-3 sets of 12 reps on each of these machines :
the row (75 lbs),
leg press (190 lbs),
arm curl (60 lbs),
arm extension(45 lbs),
leg curl(60 lbs),
leg extension(60 lbs),
fly press(45-60 lbs),
and ab crunch(90 lbs)
-An hour on the crosstrainer at varying intensity and incline

As far as my diet:
-I've started packing my own lunch(usually a sandwich, Propel water or Green Tea, granola bar, and a fruit cup)
-I don't eat out as often (I cook at home more and in smaller portions)

I usually like to do my workout routine 2-3 times a week, but I'm unable to arrange transportation(I get my Level 1 permit around the start of summer and won't have my Level 2 'till the summer after my jr year) during the school year, but am able to during the summer (we have 3 months for summer).

I currently weigh 300 lbs, and I'm in my sophomore year of high school.

Is this a good routine for the goals I'm trying to meet?
(Also, if you have any tips for keeping active when I can't make it to the gym and don't have any equipment at home to use, those would be great!)
