BB Desktop Software :: How To Reduce Amount Of Memory Allocated To Pictures?

My name is Ed and I'm a newbie. Please indulge the length of this first post as I have many issues. My goal is to get all my favorite music together to be played on my Storm, which I can also use to play through my home stereo system. So far ,there, the volume is erratic and there is some distortion.
I have copied CD's and downloaded MP3s and M4as to my computer. The downloads came zipped and when extracted, I put the folders in an iTunes file and deleted the artwork and was left with the zipped folders, which I put in a separate "downloaded zip files" folder.

(1)Can I delete these zips without losing my music? I installed the original Desktop Mgr with Roxio, didn't like it, uninstalled it, and reinstalled DM with no Media Mgr and downloaded iTunes for the second time. Meantime, I opened Windows Media Player to see what version I had and if I could use it with DM and it automatically retrieved my 700 songs.

(2)Are they hurting anything there being a duplicate of iTunes and if so, how do I get them out?
To the biggest problem: I also downloaded the BB Media Sync and when I used it to load my 700 songs to my phone, it did so for 650 of them (4.3GB) but then said I was out of memory so it didn't sync the last 50.The details showed me that I have about 3GB memory left on the phone but it is for pictures.I don't care if my pictures are on there or not, I want to be able to load 8GB of MUSIC.I used help and it said to go into DM, choose options, and reduce the memory allocated to something else, (like pictures).I did so and there was no way to do that. I tried clicking on everything and never saw any way to do what help said.

(3) How do I get DM to allocate all my 8GB available memory to music? I know I can buy a 16GB chip, but I'm afraid it's going to allocate 12GB of it to pictures.Also, and finally, it is showing 700 songs on the sync screen, but it's shaded. When I want to add,say, 10 more songs, how do I get them through the system and ADD to my phone.Does sync automatically not duplicate?I have Windows XP SP3, 9530 through Verizon, and am about a 3 out of 10 computer knowledge wise.I am going to play golf now, which presents, although completely different, an equally challenging activity.
