Hello and welcome leirbag75 !
One of the points why this forum exists is answering noob questions.
We all have learned Common Lisp at some time in our lives, and those who are afraid to ask questions will probably never learn anything at all.
One of the points in using Common Lisp is that you do not need to worry about the programming style because you can freely mix them all together in one and the same program. Common Lisp does not restrict you to use one style only. You can for example write several versions of the same program using or mixing different programming styles, compare the results, and the choose what works best. Not many other programming languages let you do that to the extent Common Lisp does.
It's hard to tell what style to use, because that mainly depends on the problem you want to solve. Therefore it's important to write real-world programs and not care too much about books or tutorials that try to tell things like "always use this style" because that's just simply not true for all problems.
On the other hand, if you want other people to read your code there are some conventions how to indent Lisp code, described for example here:
A list of free tutorials, books, and other stuff can be found in the CLiki
under Getting Started
Good luck, and have fun with Common Lisp
