I can understand your apprehension. But every guitar I've ever acquired, either new or used, needed some set-up tweaks to be comfortable to me. I learned how to do it myself some years back, and it's not, as others have said, an exact science. That said, there is no shame in taking it to a trusted shop and having a tech do the set-up. I was lucky that I had a local shop whose tech, early on, walked me through the steps for doing a set-up and how to adjust it to my liking. (This was long before the advent of the internet and when such info wasn't easy to come by.)
An interesting side note, I've had guitars that I just couldn't get to play right, as far as I was concerned. One in particular, an old strat. I took it to the tech I knew and in a very short time, he had the thing playing perfectly. (Unbeknownst to me, as I was trying to set it up, it required some fret work, which is beyond my skill set.)
