Welcome to the site!
I've always liked albinos, there is something really cool about them. As for having one as a first BP there is nothing wrong with that. All BP's have the same care requirements, and deserve the same level of care.
Females do tend to get bigger than males.
Here are some great information threads to make sure you are up to speed on keeping snakes, specifically BP's:
