SJC and not RHV I'm guessing? SJC gets tons of GA traffic, there is commonly VFR pattern work being flown there, it's no big deal to fly in there in a piston at all. You'll probably either join the left downwind from midfield or out by Moffett for 30L, FBO's are all lined up to the left side of that runway, it is very straight forward. There are no unexpected procedures other than the typical wake turbulence concerns you have at any airport with lots of GA and airline traffic mixed and usually there are minimal delays to get you in, if any.
