I'm not sure if I understand the problem exactly, but you have been pushing "command" with delete, right? That should delete things in Finder just like it did in Windows.
Also, what I ended up doing with Finder, so that it would automatically arrange all the icons in every folder, keep them the size that I like and all, right click (or control+click if you haven't turned on right click) and hit "show view options", set it how you like, then at the bottom click "use as defaults". I can't get to that on desktop, but anywhere else in Finder, you can do it, and now every folder automatically arranges and everything.
Again, may have misunderstood, but I hope I didn't
LOL, no, I didn't realize I needed to press command as well :O) Thanks for the tip, I still have a long way to go before I learn everything.
