Honors society/Greek stuff I don't get.

Don't join expecting career opportunities or extra perks.

Will it help your transfer process? Potentially. Assuming you don't know anyone in the new school, it could be a way to meet people

Will it help you join PBK? I Googled both of these and they seem like generic honor societies... If you want to join one, at least choose one specific to your major

You didn't mention what you were going to school for... if it's Computer Science, I wouldn't even recommend the honors program. Grades are important (get that 4.0!) but I doubt "graduated with honors" would look better on your resume than some work experience or personal project. Spend the extra effort doing something useful instead
