What are the most important perfmon counters to tract to create a baseline for your servers in a Central Management Server?

I am currentlly collecting perfmon counters for my Central Management Server to create a base line.  Years ago, I had a manager that had me collecting the following counters
        "\LogicalDisk(*)\Avg. Disk Queue Length",
        "\LogicalDisk(*)\Avg. Disk Read Queue Length",
        "\LogicalDisk(*)\Avg. Disk Write Queue Length",
        "\LogicalDisk(*)\Current Disk Queue Length",
        "\LogicalDisk(*)\Disk Bytes/sec",
        "\Memory\Available MBytes",
        "\Memory\Pages/sec",
        "\Paging File(*)\% Usage",
        "\Paging File(*)\% Usage Peak",
        "\PhysicalDisk(*)\% Disk Time",
        "\PhysicalDisk(*)\Avg. Disk Queue Length",
        "\PhysicalDisk(*)\Avg. Disk sec/Read",
        "\PhysicalDisk(*)\Avg. Disk sec/Write",
        "\PhysicalDisk(*)\Disk Bytes/sec",
        "\PhysicalDisk(*)\Disk Reads/sec",
        "\PhysicalDisk(*)\Disk Transfers/sec",
        "\PhysicalDisk(*)\Disk Writes/sec",
        "\Processor(*)\% Idle Time",
        "\Processor(*)\% Interrupt Time",
        "\Processor(*)\% Privileged Time",
        "\Processor(*)\% Processor Time",
        "\Processor(*)\% User Time",
        "\System\Context Switches/sec",
        "\System\Processor Queue Length",
        "\System\Threads"

I have the Task Scheduler running every 5 minutes.  With all these counters, I am inserting a lot of rows for 33 servers.  I am currious, are any of these counters less important than others on this list?  Are all of these counters important to track?  Can I eliminate any of them?  What are the most important perfmon counters to tract to create a baseline for your servers in a Central Management Server?
