Help My GTD Setup!

Well, I've been using GTD for quite sometime now and I've kind of figured out what is best for me, though. I need some help with some of the stuff though. For example, I don't know what do with certain projects I want to do. Some of the current projects I want to do is getting my room organized, selling some of my belongings on E-Bay and such. These are 2 of my projects that I don't know what to do with. Does anyone have any suggestions for planning a project? I've tried backpack, but I don't like that and I am currently using GNotebook but I've been looking for something better.

Tools I currently use:

• Remember the Milk
• Joe's Goals
• Google Calendar
• MoneyTrackin
• Netvibes (feeds and GTD integration)

I was also wondering if I should carry something physical around with me besides a PDA or something since I don't have the money for one. I was thinking about carrying around a small notebook but I don't know what kind I should get and such.

Help me, please!
