I would imagine that Nublar was destroyed after the movie, like it was at the end of the book. If not by the Costa Rican Army, then by mercs hired by the board of InGen in an attempt to hide the snafus.
As for keeping everyone quiet, it's not addressed in the movies other than mentioning non-disclosure agreements, but in the novels everything was compartmentalized so that outside contractors wouldn't know what was going on. For example, they probably put out a call for someone to design an electric fence that can carry a charge of x volts, is x feet tall, and can withstand x force and put in an order somewhere else for the materials to build it, and had someone else build the fences. It mentions something like this when it's explaining why Nedry is so ticked at having to fix things. They basically gave him a core system to build and said things like "we need a generic output module" and a generic module that reserves "3x10^9 fields" for data access and writing. They never told him what it was for and never told him what the subsystems would be, then had someone else program other modules with more detailed focus, so he was mad that they were on his case about there being boatloads of bugs. Basically only the Tican workmen (probably also under an ND) and the Park staff knew what was going on.
As for Skynet...The world-wide network that gets set up by the virus version in 3 would've been toasted, but given its core was in an electronic warfare facility, I would imagine that it was EMP shielded (such things do exist IRL). Plus it was out in the middle of nowhere and had used the machines on station to kill all the personnel. It could've fired nukes in a pattern to avoid its core. And given that it had infected the entire defense network of every country in the world, I would imagine that it survived remotely at the hardened command installations in each country (e.g. NORAD in the USA, Kremlin bunker in Russia).
