Re: Formatting Questions/Woes....
TikiWiki's typographical details are generally specified with CSS, so to modify them, you need to find what CSS selectors are involved and then modify the theme stylesheet, or add a custom.css to the theme's directory in styles/. I recommend using Firefox and the Firebug add-on to inspect the displayed page and find what the relevant CSS selectors are. This is needed for your top four questions.
If I recall correctly, the code block is in < pre > tags, which would mean code content isn't wiki or html parsed, but is displayed as it is input. If the brackets around tags aren't displaying, try using the html encoding for them (& lt ; - without spaces - etc.). This may be a side effect of too-intense security sanitizing but has to be worked around, for now.)
