Like has been said by others, just put the appropriate tires on for the terrain you will be riding in (no need to replace the wheels). Just ride it and as you 'vibe' with the bike you will know of components of concern. What is somewhat typical is the saddle if it is unbearably uncomfortable, but then there is the quest for the perfect saddle that works with your butt. Dont bother with over concern about weight and swapping things out for lighter. Just ride and enjoy your bike and replace/upgrade as the need arises. These bikes if you are not careful can bleed you.
The Honda analogy is perfect.
