2. Am I ready?
The list of reasons for starting treatment earlier than later only gets longer as the supporting data keeps rolling in. But that doesn't mean it's obvious when you should start. The biggest variable in sustained treatment success is you: the person who will have to take meds the right way, every day, indefinitely.
Today's first-line treatment regimens are quite good, but they still require excellent adherence (not missing doses) to avoid the development of drug resistance. The number of possible antiretroviral combinations is finite, and they don't really get easier or better. In fact, the regimen you start with may well be the easiest, most potent regimen available to you -- the kind of thing it would be a shame to lose by taking it when you're not ready.
