Once you have got the hang of laying everything out you wanna start looking at the FX panel dude!!
Click here......
...and you get the 64 channel mixer....
Now if you go back to your Channel Settings look at the top right corner and there is a function that enables you to send this sound to one of the FX chchannels.
Here I have a kick and i am sending it to FX channel 1......
This now routes the sound into channel 1 of the mixer, and selects it like this.....
Now it is in this channel you can load effects units into it that will change the sound accordingly.
To load an effect unit click here....
...and you will get a drop down list of all your available effects (probably only the fruity ones until you find more)... like this...
All these different effects units will effect the sound in a different way. From personal experrience the best way to learn what each unit does is to go thru them all and listen to how each one changes the sound!
(Can i ask at this point do you have a good set of monitors?? Cos it does really make all the difference here)
To make a kick drum sound professional you will need effects such as EQ, Compression and possibly Reverb depending on what type of kick you want! There is more you could add but just start off with these.
Select the Parametric EQ from the list and it will appear like this.....
When this appears start having a mess around with it. You will get to grips with EQ'ing just from playing around here, left hand lower freq, right hand higher, very simple but can make so much difference to a sound 
Continue to add more effects in this channel like i have done above and mess about with them as much as you can. After a while of doing this you will soon start to learn how to manipulate a sound the way you want it.
Once you have finished with your kick move on to hats, only send these to FX channel 2. In my opinion with sounds like hats and percussion it is often good to pan left and right to widen the sound in the stereo field, if you la yeverything straight down the middle it will become cluttered and wont have much of a stereo effect. In the list of effects units there is pan control's and stereo widners so have a play around with those
Another thing to notice about the mixer is these controls here....
The top set of knobs control how much your chosen effect actually changes your sound, just like turning the effect up and down, not the sound!!
The bottom knob is a built in stereo widner, turn it right and it widens a sound, turn it left and it does the opposite, which makes it mono. I always mono my bass and my kick, sounds better IMO 
Hope this is enough to get you going dude, not sure my explanation's are too good but you should get the gist of it
If anyone else wants to add anything or tell me i'm wrong in what i'm doing go ahead, i havent got very far so aint really one to be giving much advice, this is just how i do it
