Добро Пожаловать!

1. You have to believe in yourself - this is a long and arduous journey without a guaranteed result in the end and you have to want to get it as it will be hard and painful (getting recommendations, writing excruciating essays, etc). Many people have got in, so the answer is absolutely but depends on what school and amount of effort. MBA application is a lot of work as you know but it also requires personal change.
2. I know many applicants don't think they stand out. That's not true, or at least you have to make it not true for the next 9 months. You are absolutely special and unique in a number of ways. Believe in yourself and think great things. Do great things, and do the things you always wanted to get done now. If you are still feeling you need extra help on your profile/resume/etc - think what you are missing or what other people with unique profiles did, accomplish, engage in and pursue - that will make you a stronger and more interesting individual all around
3. You will need to either explain the low GPA (e.g. nobody in school received GPA higher than 3.0 or 3.2) or you will need to build up an academic profile in some other way (training, courses, etc). GPA is a very important part of the profile and is the most influential factor in your bschool graduation and success, at least based on the Adcom perspective.
