What are the absolute must-have things I need to get for a brand new tablet? I just treated myself to a Samsung Galaxy Tab for my birthday and honestly I am so confused by all the extra stuff in the store. I have never owned one of these before and I feel like a total idiot looking at all the options. I saved up about 450 dollars total and after buying the tablet I only have like 60 bucks left in my budget for accessories so I really cant afford to buy stuff I dont actually need. I live in a small apartment in Seattle and mostly plan on using it to watch movies while I am on the treadmill or maybe reading some books before bed.

Do I really need one of those glass screen protectors or are they a scam? I am super clumsy and drop my phone all the time so I am scared of breaking the screen on day one. Also is a keyboard necessary if I am not using it for school or work? I saw those floppy cases that turn into stands but they look kinda flimsy to me. Some people say I need a special pen too but it didn't come with one. I just want to make sure I am protected without wasting money on junk I wont use. Sorry if this is such a beginner question I just have no idea where to start...
