Unfortunately natz eligibility isn't as simple as reading each rule in isolation to determine whether you qualify. IOs look at your overall pattern of behavior and (by implication) their perception of your intent, and adjudicate the case as they see fit.
If I'm understanding your initial post correctly, you resided (and were also employed) outside of the US from 3/06 thru 7/07 (16 months) and made one short return visit to the US in 11/06. That puts your individual absences at 8 months and 8 months respectively, both of which are over the 6 month threshold for presumption of breaking continuous residence.
Having a single absence over the 6 month threshold puts the burden of proof on the applicant to demonstrate they did not break continuous residence. Having two trips back to back (essentially, one long trip) makes it pretty much impossible.
Since you held a reentry permit, there should be no problem with your LPR status. Its just a matter of how long you now have to wait to become eligible again.
Note: I'm not a lawyer, and my opinions are based upon the collective experience of myself and others who have contributed here. You may wish to seek professional advice and/or apply anyway - pretty much the only thing you risk by applying now is the application fee.
