There are two environments for setting quotations apart from surrounding text: Quote for short quotes and Quotation for longer ones. Computer code (the LYX-Code environment, also used in the Tutorial for the long typing examples) is written in a typewriter font; this environment is the only place in LYX where you're allowed to use multiple spaces to allow code indenting. You can even write poetry using the Verse style, using Return to separate stanzas, and C-Return to separate lines within a stanza. See the User's Guide for more complete descriptions of all of the available LYX environments.
