GTD on RTM

I'm updating my Remember the Milk set up for my Getting Things Done (GTD) system. My previous system was working fine before the semester started, but once I needed to track actual topics of study for each individual course it didn't work out. I'm hoping that this updated system will help me better organize my school life (beginning PhD math student).

Locations:
Obviously location based information
Home: Tasks that actually require me to be physically present at my house
Work: Tasks that require me to be at the Math office.
Anywhere: Tasks that can occur independent of my actual location. Examples include homework

Tags:
These will be used for non-location contexts required for accomplishing the task

@phone: need to call someone
@mac: need desktop computer
@online: need any web connection
@email: send email
@droid: (probably unused) require my phone
@iphone: e.g. required for app testing
@errands: Generic items I need to purchase
@: Tasks which require talking to people

Lists:
Major projects will have their own lists. Drawback I can see so far: no keyboard shortcut on the web app to change the List folder.

Inbox: Holding place for all tasks coming in that need to be processed. This should be emptied frequently
P-Complex: Topics I need to learn/study for complex analysis
P-Calculus: topics for advanced calculus
P-Algebra: For this semester, Linear algebra topics
Staged: Tasks which aren't tied to a project but need to live somewhere

I may add new lists like P-AnalysisQual, but at this point, I don't think that's quite necessary as a real list since it would combine topics of Complex and Real Analysis, and these will have overlap with P-Calculus and P-Complex.

I'm am going to be continuing to use smart lists to join topics. My current examples are People which matches all individuals which are people tags; my Mac smart list combines tags of @mac, @email, and @web; and I might introduce something like Classes which will just combine all topics from P-Complex, P-Algebra, and P-Calculus.
