Honestly, rather than getting caught up in the "exchanges" and stuff like that, I would focus on just eating 5 portions of vegetables a day.
When I started this, I tried always, to go full out on a plan and it didn't really work for me, in the sense that I would start feeling deprived and I would hate that I'm being "forced" to eat a particular way that wasn't "natural".
Since you don't like veggies so much, I would start just trying to incorporate any vegetables (except the starchy ones) into your diet. Carrot sticks and celery sticks with peanut butter (or any nut butter) as a snack. Have some apple slices with it, so you can increase your fruit intake too since you like fruit.
Make a soup and add lots of vegetables in it (I like vegetables mixed in like that). I also make chili with carrots, celery and onions, all ground up in a food processor and it mixes in with the meat in the chili and you can't tell it's celery, carrots or onion, but it adds great flavor. French cooking is based on that mixture, called "mirepoix" (http://en.wikipedia.org/wiki/Mirepoix_%28cuisine%29
) and it's actually a great way to add vegetables to any dish.
Try different combinations of salads until you find something you like. I discovered I liked sweeter salads with fruit mixed in and nuts, than savory salads like a Cobb salad.
As for lean protein, you can look at chicken, but cow beef is also an option -- you just have to look for lean cuts of beef. Also, if you like fish or seafood, white fish is very lean as well as shrimp. Pork can be very lean again, depending on the cut. If you like lamb and other meats, they have also the "lean" version. Grass-fed beef, pork, and lamb is leaner than corn-fed, too. Eggs are also considered lean protein.
