OK, let me see if I can help
Your droid has three main areas
1. Your apps drawer, the middle icon that when you click all the apps appear, and you can scroll up and down to see what you have installed
2. Your home screens, which is where you can create folders, drop apps, shortcuts and widgets. Usually there are three, and you can move left or right
3. Your notification bar, which is irrelevant in this discussion
OK
Where do you have the apps that you want to delete, in the apps drawer or on the home screens?
If you have it on the home screens, click and hold the icon until you can drag it and then drop it in the middle of the bottom screen where a little trash can will appear and you can delete it. This only works for items that are stored in the home screens, like app shortcuts, widgets, shortcuts and folders
If the app appears on the app drawer, you cannot drag it from there to delete it (at least not in the stock browser), you need to go to your main settings - applications and manage applications. From there you can uninstall the application, this will remove it from the app drawer and any home screens.
Hope this makes things a little clearer
