Hello new friends!

I am nearly done with the GTD book, and I am trying to get a few conceptual questions answered.

1 - Are ongoing everyday tasks such as:
Checking for new orders, sending those orders to vendor via purchase order, check for new tracking numbers, send tracking numbers to customers.

These are divided by vendor in some ways, but the orders come into one website. So I am not sure if these actions are really contexts, or projects? If they are projects that are just permanently daily tasks, and not something that are ever going to be "completed"...

2 - Since I am always with my laptop, and phone, I am not sure the best way to setup my contexts? Should I divide things up by time during the day? ... like "morning work", "afternoon work"? The thing is I can pretty much do any task at anytime. Its nice, but frustrating as well.

I am planning to use outlook as my trusted system, with the GTD add-on. 90% of my items are digitally stored, or at least have the key reference digitally.

Your advice is welcome!
