How to start with CE

[CrossSleet]

Hi there,
i have questions about starting my own collection. What should i do and shouldn't.
I always feelt like a gamer of sort but being young/not having money etc. made me rather PC player with piracy copies than original ones.
Now i can live by myself and started being true gamer like 3 years ago.
Now i have Nintendo Wii, PS3, PS4 and Xbox360 and nice collection of games. But they're just games. Standard copies, unpacked and all. For awhile im wondering about doing nice stuff with this but i have some problems.
First is, i want only games i like in my collection. Didn't like Skyrim so i sold it. Problem is- how can i buy CE for game i don't know i like? But if i buy standard copy and like it then i feel like buing CE is waste of money.
Should i sell standard copies of my games and buy CE instead? Like for Dark Souls, Fable or Dragon Age?
Next is- i only considered CE of games but i see many people buy not only that but other items of the franchise like press kit's, figures (not from game dev) and all. Should i do it too?
My only CE now is Naruto 3 True Despair and i like the feeling of figures and other stuff. Dunno what should i do
Next - what about CE with great stuff but not in my country? Like: Tales of Symphonia Chronicles is great in US edition but poor in EU, should i get US? More problem are great jap editions (i love Dragon;s Dogma jap watch) but i won't ever play this editon of game (due to region restriction of xbox360 and all). Should i abadon the idea?
