The queue time is perfectly fine, for the reasons already stated; shortening the queue time would just mean more quickly-abandoned stories clutter up the website listings.
For me, added WFG staff would be good for more main site-related functions. Editorial reviews of newer stories or ones that haven't gotten a lot of love; interviews (apparently those used to happen: http://webfictionguide.com/articles/interviews/); news posts for "important" stories (which ALSO used to be done http://webfictionguide.com/articles/bulletins/); checking to update the listings for stories that have been cancelled, or whose website has disappeared, etc. That sort of thing, mostly just maintenance.
A lot of this sort of stuff seems to have disappeared around 2009, but now that web fiction as a medium is a lot bigger than it was a decade ago, I think it would be really beneficial to kickstart some of that again.
