Should you protect your comics right way?

Im very new to collecting any sort of comics. I never read any comics growing up but i got into the walking dead comic series i own the paper back volumes 1-17. Recently i liked series so much that is started buying issues as they come out i own issue 100-104 now. So i dont really know anything about collecting them will they be worth that much later on i should do it right away? Also im wondering what dimensions i would need for comics im storing for the boards and bags. I assume all issues of walking dead are all same size? 1-104? Also should i store them in comic book store boxes already i dont think i feel ill be wasting space but apparently you should store them in correct way or they could be damaged just in a stack.

If you want to protect them you should do it right away. You will be fine with standard sized boards and bags. The boards so be acid free.
