Removal of beta service pages/notability issues 

Hi Henrik

I have edited the entry on my father, Keith Lawrence who flew in the Battle of Britain in 1940.  He is still alive and I see him every week.  As well as knowing his date of birth and his general life history, I have access to his Pilot's Flying Logbook, giving completely accurate information about his time in RAF - but this is not a published document.   This information and the Logbook are primary sources, which I have used for the Edits I have done.

I have noted several administrative points:

(a)  It says "This is very much a beta service and may disappear or change at any time", presumably because of the low numbers of people viewing the page.
(b) "The topic of this article may not meet the general notability guideline. Please help to establish notability by adding reliable, secondary sources about the topic. If notability cannot be established, the article is likely to be merged, redirected, or deleted. (August 2011)"

My questions are: 
1) If I add secondary sources (confirmation of material relating to Keith Lawrence which is in various published books) does that reduce the liklihood of the article being merged, redirected or deleted?  Or might it disappear anyway, because it is a 'beta service'?
2) If I spend time adding references and citations to secondary sources, is there a time limit for doing this, please?  (For example, 6 months from the August 2011 date mentioned above?)

Basically, I would like to know, please, if it is worth me spending time providing secondary sources if the article will be deleted anyway because of the low number of 'hits' the page receives.

Thanks,
