Then, how do I upgrade KSP?
Building upgrades cost funds and can be requested by right clicking the building in question. The KSC and each of its buildings are biomes which can be examined for science (see building articles for details). Additional biomes become available for some buildings as they are upgraded.
Furthermore, how do I update KSP on steam? If you have the Steam version it will update automatically - whether you want it to or not. If you got it directly from KSP go to kerbalspaceprogram.com, click on 'Store' and log in from there.

How accurate is KSP?
Almost exactly 48% realistic. On first glance it feels very realistic but once you start looking at details, you find that almost nothing is quite realistic - realism of physics is reduced - mostly intentionally - to improve gameplay.
