There is a free app called LockMenu that has customizable sliders on the lock screen. Might be helpful since the phone does not have a dedicated camera button.
I use Go Locker. I haven't messed with much for the locker. The background is from the anime Guilty Crown. Nothing too special about the lock screen since I only look at it for about 5 seconds.
My home uses Sakura Pro Live Wallpaper (falling flowers and petals), Go Launcher FutureWorld theme.
Widgets: Battery Health Bar widget (zelda hearts), Battery Widget by COMXP (Cat battery notifier (happy cat equals happy battery =^_^=)), Advanced Clock Widget, Memory Status Widget.
