Help my brain out...its tired

[ElectricShock]

Well i am new to this site...i have no blu ray movies
i just purchased a 52 inch lcd 1080p hdtv from best buy
and i got a tv stand for it
i also bought a 40 gig ps3
Well i took it back today--the ps3
i have no games or blu ray movies
When i heard the metal gear bundle with the ds3 controller is coming out and its 80 gig...thats just 100 dollars more...i figured why not?

But i dont want metal gear...i will probably trade it in for a second ds3 controller....i do want the 80 gig ps3 with the ds3 controller tho

I want to get motorstorm...uncharted...ratchet and clank...THEN when they come out madden 09..motorstorm 2....thats about it for now

Theres about 37 blu ray movies i would like to have also...

I have about 300 dvds...And im battling back in forth with my brain to figure should i take them to this used store and sell them all just so i can stock up and start a blu ray collection and get some games...and was it dumb to take back the 40 gig and try to get the 80 gig one.....

Should i jump in and do all this crazy crap...i dont want to regret it down the road tho...

Anyone with a past experience from when they started out going blu
or anyone with a suggestion or idea
DEEPLY appreciated...
Thanks
