I have n00b questions, please answer =)

Hi, I searched around first before I posted and found a few answers before posting (ie: black bars and what's coming out on blu-ray). But some things I didn't find at all or have to deal with my setup.

I have a PS3 connected via HDMI to my Samsung LNS3251D 32" LCD HDTV to watch Blu-ray and play PS3 games.

Whenever I load a game/movie, the screen goes blank temporarly and makes as someone else said a "popping" or as I say a "crackeling" sound then proceeds as normal. I have grown to kind of ignore this, but why does that happen?

When I have the PS3 set to 1080i I get TONS of ghosting when playing games, it is especially noticeable when text appears on screen then goes away to another screen. So I have taken it down to just 720p.

I get tons of grain when watching movies though? How do I fix that? 300 and Ocean's 13 look just awful!!!

Last one, unless I remember another, is when I go to the store and look at the HDTV and Blu-Ray setups the movies look like they are shot by a "camcorder" for a lack of a better word. It kind of looks like something out of the public acces channel. I am not sure how to describe exactly. It looks like the entire movie is being filmed live in front of you I guess. When I bring home the same movie, it does not look anything like I saw it in stores. Again why is that?

I feel like I am two years old all over again.
