Most probably yes. At least it makes everything consistent.

Yes, I believe you're in the right path, except for a little error in the
line below:
ajax('track'), {
It should be
ajax('track', {
And adding an element: null or element: [some element] to the object you're
passing as the second parameter of ajax().

No. onActivate() is called for every request to the page, regardless if
it's an event or page render one. You need to remove the expensive code
from onActivate(), or at least only call it when needed. You haven't posted
any Java code or pseudocode, so it's hard to help you further.
