Reply to Song browsing on cdj's

So my setup now consists of 1x CDJ-400, 1x CDJ-350 and a A&H Xone 42 Mixer.

I had previously planned on using these through traktor (not scratch) but I then decided to give it a try without any software/computer. I am absolutely loving everything thing about mixing without software except for a few things:

1. The cdj screens are just too small....Its a real pain going through my songs especially ones that are listed by the artist first and not the song name (i use my external HD and USB Flash drives currently). I have both a Windows 7 desktop that I built myself with specs that are near untouchable with a 22" LCD monitor as well as my 13" Macbook pro. Both have traktor and all my music. Basically i would love to have a way to display my music library on one of my computers and be able to select the tracks using the cdjs. This doesnt need to be through traktor but i am pretty familiar with traktor so any ideas let me know....

2. The cdj-350 doesnt have any effects...this really annoys me as i actually love everything about the cdj otherwise (besides the screen). Any simple solutions here?

3. I have looked around everywhere but cant seem to figure this out...what are the 'Control' plug input in the rear of the CDJ's for? Really bothering me...

4. I am really lost on setting cue points and loops and saving them. I dont believe i can do any memory features on the 350 but the 400 i know how to set and save either 1 cue or 1 loop per song and i can recall whichever one i save. Is there a method to saving more than one cue and/or loop per track though?

Thats all i have come up with so far. Any and all responses are appreciated!
