There are several strands of licensing of which the ground is only one. It's all detailed at the link below.

In addition to that licensing is being used for a number of different purposes - as ground criteria for Professional Game leagues; as SFA membership specifications; and as eligibility criteria for the Scottish Cup (if SFA get their way).
Clubs currently in HL & LL have to obtain a licence by next summer. As you say, Stirling should already have the ground aspect ticked by merit of the groundshare, and the new stadium at Edinburgh University has been built with licensing in mind: the Border Telegraph says they only have to complete paperwork to obtain their licenses... Cove are well-run but hamstrung by the cramped pitch and facilities at Allan Park so their problem is the opposite: the P&J says they intend to ground-share if their new stadium isn't ready in time... Vale of Leithen lack a rail around the pitch, disabled access and a disabled toilet, and signage: the local press says they'll need to find £8,000 to finish those works. Clubs need an Entry license for HL & LL; an Entry with Bronze floodlights for SPFL1 & SPFL2; and, IIRC, a Bronze with Silver floodlights above that.
Licensing is also the standard asked of new clubs wanting SFA membership. It replaced previous seperate criteria which were tougher.
And SFA wants to standardise cup entry to licensed clubs only, originally targeting "in 2016". However they tried for 2015, i.e. next season, at this year's AGM; but it failed to obtain the necessary majority. This could affect unlicensed members, and/or qualifiers.
