BB Curve 8500 :: How To Delete / Save Pictures

Okay, please excuse my ignorance guys.. xD.I just purchased two BlackBerry Curve 8530s from Sprint. I am pretty tech savvy, but there's some things on this phone I just can't grasp in the two or three days i've had 'em:

Deleting Pictures: Okay, so i am in my Media folder, in the pictures. I select a picture and press the BlackBerry button and select delete. Then it says it is read only, and when i delete it, the icon is still there. I've tried turning the device on and off and it's still there. Figured this one out myself. I hooked it up to the Desktop Manager, and suddenly all the pictures I had taken appeared. I was also able to delete them using the "BlackBerry key" then "delete". It didn't give me that read only option.

Saving Pictures: So, for whatever reason, i can't save anymore pictures. I don't even know how I saved the first 12 pictures i took.. but now it will not save anymore. What the heck happened? xD I have a 2GB card in my phone.. surely those 12 pictures didn't fill that card up... Figured this one out myself. I hooked it up to the Desktop Manager, and suddenly all the pictures I had taken appeared.

Buying Ringtones: On my old LG phone, i used to purchase ringtones from RealTone Jukebox.. where they had snippets of songs that I could download for a crazyhigh fee. Where can i purchase real music ringtones for the BlackBerry? Do i have to make them myself?

Moving Media to my PC?: I went through the Sprint Music Store that came with my device, and purchased two songs. I want to know if I can get these songs off of my BlackBerry device and to my PC. Also, if anyone knows what format they're in (if they've purchased from the Sprint music store before).

Purchasing another Memory Card: Where's the best place to purchase one of those mini memory cards? A friend of mine has like, a 24 gig one.. and i currently have a 2 gig (which, i should mention, is more fricken memory than i have in the computer i'm writing on right now xD) How will i know if the card is compatable with my device?

WTF @ Red Light?: Every so often (it may still be doing this, i'm not sure), the little red light at the top of my device will blink even if i don't have a low battery or any new messages. It first happened lastnight when a friend sent me 3 IMs at one time. I had to restart my device and i think it stopped. Earlier, it happened again (I had multiple new messages) and this time, every time my screen lit up, the indicator was solid red.. not blinking. It may still be like that now, but i'm not sure. My device is in the other room and i'm too lazy to check xD. Why is it doing this? How can I make it stop?

Turning the Camera Noise off?: My device makes the camera shutter noise, even when on silent. Is there a way to stop this?

Auto Keyboard Lock: I EPIC purse-dial people. I see there is a Keyboard Lock button in the BlackBerry Dashboard (is that the correct term for it?) But i want to make it to where the keyboard auto-locks after a certain amount of time. Is that possible? I saw somewhere about pressing the mute button will lock it... is that the button at the top/center of the device?

BlackBerry Key?: Okay, don't laugh, i know i'm retarded. But, the key to the left of the track pad.. what the heck is that called? It's got the BlackBerry logo on it... is it called the BlackBerry Key? I know, I know, i'm retarded and could probably flip through the manual to figure it out.. but still. I might as well ask now xD

Choosing Icons to display on the main screen: When I added an e-mail address, it put an icon on my main desktop, in the row of icons on the bottom of the screen. (where my background picture is and all that). Can we choose which icons we want to display on the main screen? I don't really need my calendar icon there, as I know i won't use it. I'd love to move the Keyboard Lock button there though.. is that possible?

Speaker Phone?: How do i make Speaker Phone happen? xD

Theme Studio (Software, not device related): Has anyone used this? Is it pretty user friendly? I'm tech savvy, but I don't want to just download a ton of programs to my PC that i won't use xD I'm working on getting the Desktop Manager and it's taking forever. I want to make themes, but i'm curious how user-friendly this program is.. or if it'd take a graphic design graduate to use it xD
