Microsoft has posted the recommended settings for event log sizes in Windows Server 2003 and in Windows Server 2008 (link), but I was wondering if anyone knew if there was something somewhere which posted the same information for Windows XP. Most importantly the Recommended maximum total size for all each log and all logs

It would appear that Microsoft themselves do not specify the recommended event log sizes for Windows XP (unlike the article you linked to for Windows Server 2003/2008).
Despite this, there is some information out there from other large organizations, that offers default sizes and recommended size settings:
The Computer Security Resource Centre at NIST, in its publication entitled, "Guidance for Securing Microsoft Windows XP Systems for IT Professionals: A NIST Security Configuration Checklist" states:
For the Application log, the maximum size should be set to 16384 kilobtes. For the Security log, the maximum size should be set to 81920 kilobytes. For the System log, the maximum size should be set to 16384 kilobytes.
The NSA document, "Windows XP Security Guide" states:
Table 3.18
Event Log Security Setting
Recommendations Setting EC desktop EC laptop SSLF desktop SSLF laptop
Maximum appl. log size 16384 KB 16384 KB 16384 KB 16384 KB
Maximum security log size 81920 KB 81920 KB 81920 KB 81920 KB
Maximum system log size 16384 KB 16384 KB 16384 KB 16384 KB
(where EC = Enterprise Client & SSLF = Specialized Security - Limited Functionality)
And finally, the DISA publication, "Windows XP Security Checklist" states:
If any of the following conditions are true, then this is a finding:
If the value for “Maximum application log size” is not set to a minimum of “16384 kilobytes”, then this is a finding.
If the value for “Maximum security log size” is not set to a minimum of “81920 kilobytes”, then this is a finding.
If the value for “Maximum system log size” is not set to a minimum of “16384 kilobytes”, then this is a finding.
Of course, the default sizes of 512kb for each event log, as configured by Windows XP itself upon installation, could be considered the "default" sizes.
