No, who files first is not a factor.
Spousal support, which used to be called alimony, is calculated based on an effort to maintain both parties' standard of living. Whether you're entitled or not can't be determined based upon the information you posted.
If the pension was earned or accrued during the marriage, yes, you're entitled to a share.
You should strongly consider consulting a local attorney and discussing your situation in detail!
