It means to keep playing with every aspect of these tools, it means to do some web searches (read articles and watch some video tutorials), it means to take some of the suggestions here and try them out. Keep trying things until you find what you like and works for you. The desktop environment and applications have so many options its impossible to go over them all really. You can even expand on many of them with plugins, custom actions, etc, etc.
You did a good job asking specific questions and stating what you want, but I "believe" that I gave you one of the things you wanted. Take a look at the thing people suggest, we are trying to help you on your journey, but we can't take the trip for you and we can't read your mind.

Going back to my earlier post... there are Panel plugins that may help... I guess you want steps?
Right click the Panel > Panel > + Add New Items > Launcher >> Launcher Window open > click '+' plus sign > find application > click + Add ... rinse and repeat.
The above also has the option for URLs and custom items too. Lots more great things like this available if you "keep plugging away".

Edited: cause my spelling on the phone stinks a lot
