I was really looking forward to bake a cake with all the new hints and tips i've learned from this site! I even stopped at michaels on the way home and bought a spinning cake tray, and a tip for icing! but once again, it was a disaster!! can I have some tips?
Well I think I iced it way too soon, (5 minutes out of the oven) i was using wilton's icing and used my icing tip but as soon as i started smoothing it with my icing knife it took off too much and by the end i could see the cake base and eventually i started getting crumbs break into my icing and now its just nothing but a big mess!! Im tired and frustrated!!

You need to let the cake cool completely before icing it. I would wait at least an hour. (I don't even turn the cake out of the pan until it has been out of the oven for 10-15 minutes (depending on size).

Aww, I'm sorry you are frustrated. Take a deep breath and make a plan for next time.
I bake the night before I need the cake, and never ice/decorate it until at least 12 hours later. The cake needs time to cool completely and to settle.

Fresh cake right out of the oven is too hot, of course, the icing will melt. Even a couple of hours later, the cake is still too soft and tender to ice without falling apart unless you are very, very experienced.

I recommend you try icing the cake using the #789 icer tip again. You use it with a BIG icing bag, 18" or bigger. With the zigzag side next to the cake, you turn the cake as you squeeze and it applies a 1/4"x1 1/2" strip of icing. You do that till the cake is covered, then smooth out the "seams" with a spatula. Here's another opinion about the icer tip:

Good Luck!
