Newbie needs help :) Please.

Hello guys! you're probably going to hate me...I am completely new to this...I've been working with my computer for quite some time...but getting deep into programming I am just at the start line, so please bare with me.
I want to learn to crack, debug etc...I've checked the tutorials and I found a nice tutorial and I have even downloaded it to my computer, but I don't have all the tools needed for this.
Where can I find these: IDA and HexWorkshop???
Please feel free to tell me where exactly I should begin...
I appreciate any comments.
Thanks,
