If she's the one disabled it seems like she should be the one to get all of the disability money (lump sum and monthly), no?
If pension was earned during the marriage she probably is entitled to a share (50% of what was earned during the marriage). If you're talking about 401k or IRA that would probably be a lump sum transfer, if it's defined benefit she should get paid her share as you get paid.
As for alimony if your incomes are very different she could probably get you tagged with some. If you think she has more income potential despite her disability that she's choosing not to pursue you could likely get lower alimony but you'd have to convince a judge that she's voluntarily underemployed - that she has skills/abilities AND that there's a job market for those skills. If she's got significant disabilities (and depending on her age, prior employment history, education, etc.) that could be a tough thing to prove. And you could also get tagged with cost for retraining and rehabilitation.
So my honest assessment (not a lawyer and don't know NV law) is that you're kind of low-balling. Put yourself in her position, would you be able to live comfortably,
pay bills and eventually retire on what you're offering?
