I can't think of any way to do this with simple regexps, . . .

Then don't use a regex. Why does everyone think that all string manipulation should be handled with a regex?!? Use a simple character-by-character parser, noting state as you move through the string.

# UNTESTED !!!

my $in_quote = 0;
my $in_bold = 0;
my $final_string = '';
foreach my $char ( split //, $string ) {
    if ( $char eq "'" ) {
        $in_quote = 1 - $in_quote;
    }
    else if ( $char eq '*' && !$in_quote ) {
        $final_string .= '<';
        $final_string .= $in_bold ? '/' : '';
        $final_string .= 'b>';
        $in_bold = 1 - $in_bold;
    }
    else {
        $final_string .= $char;
    }
}

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or or How to display code and escape characters are good places to start.
