You've got the right idea.
Smart Balance spreads usually contain soybean oil (omega 6, which we try to avoid in the Zone) so It would be best to switch to real butter, or light cream cheese, or even a drizzle of olive oil.
You can work in more veggies if you like, also (refer to the Grocery Additions list, http://www.zonediet.com/GroceryAddi...ult.aspx).
You don't need another snack after dinner. On the other hand, if you prefer an evening snack, you could eat 1/2 of your dinner selection and then eat a snack later (I do that). For more ideas, you could check out my ZoneFast meals in the link in my signature below. Note that I eat closer to the men's recommendation because my daily protein requirement is higher than the average woman's.
You'd want to increase to more than a quart of water a day. The recommendation (refer to the Grocery Additions list) is 1 ounce of water for every pound of your weight.
Have fun with it!
