Hi,
I don't think that what you've found is likely to be terribly relevant. Unless the User-Agent has been faked, that's just normal Google crawling.
You're looking for anything that appears to concern a Perl script. POST operations are also probably of particular interest, rather than GETs. At least one POST was probably involved at one point to invoke the malicious script.
Note that there will be separate log files for each site on your server, so you will need to check each Apache access_log that exists on your server in case the exploit was started from another site or location than your WordPress site.

Doing that now but since that was the wordpress install I thought I'd look at that one first. Lots for logs to go through.
