You don't have to be an expert in Perl, but basic understanding is 
necessary to install and run Cricket.  The know-how of configuring 
Cricket and how SNMP works on the other hand doesn't have much to do 
with Perl.

Using the terms "disk and CPU performance" is unspecific.  On Unix you 
have 1 minute, 5 minute and 15 minute average system load, there also 
are "CPU stats", which are shown by "top" but are not queryable by snmp 
currently (but Cricket can read such values from /proc in Linux).  For 
disks you can monitor IO throughput.  Is this what you want?

The "systemperf" Defaults sample-config file

http://cricket.cvs.sourceforge.net/cricket/cricket/sample-config/systemperf/Defaults?view=log

can serve as starting point for monitoring a Unix host running

	http://net-snmp.sourceforge.net/ .

Did you install the snmpd from net-snmp?

As an alternative to supplementing this config tree Defaults file it 
might be easier to use the tool genDevConfig to generate a Cricket 
config file for you.  I have never used genDevConfig though.

Once you are so clear which values you want to collect that you now 
their SNMP object ids, you can run cricket's collector, read and 
understand its log output, making sure that the currect values are 
stored in you rrd databases.  Only then you can think of showing those 
values as graphs.
