install patches on vmware esxi 4.1

I have a lot of esxi servers with build number        348481(esxi 4.1 update1). Servers are managed by  2 Virtual centers servers. Also I have SiteRecoveryManager 4.1 installed and configured.

According to our vulnerability system , there are couple of patches that need to be installed , actually it detects all of the patches after my build and recommendations are to install them.

As I understand from the articles that are on the internet esxi patches are cumulative, so I only need to update to the latest release -ESXi/ESX 4.1 Patch 8       2013-04-30       1050704. Is this correct. Do I have to install 4.1update 2 before this update?
Also do I have to make first an update of Vcenter servers?
According to the interoperability matrix, if I update esxi and vcenter , I need to update SRM software also. Also I see that esxi updates contain vmware tools. Is this mean that I need to update vmware tools on the virtual machine also?
Is there any order that I have to follow during the installation of all of the above updates?

The patches are cumulative, so you just need to install the last patch for ESXi 4.1 U3a.

You will need to update vCenter Server and SRM (first before the hosts).

VMware Tools can be optionally updated in the VMs, no immediate hurry, unless you notice VMware Tools fixes some issues you are experiencing.

this order....

1. vCenter Server
2. SRM
3. Hosts
4. VMware Tools (optional)

I would wait, to the next Windows Patch cycle todo the tools upgrade.

Also be warned, that your vulnerability system tester, may still trigger, after installing these patches, so UNLESS you know for certain, that these patches will fix these issues, don't chase updates to fix them!

Many VMware Admins chase patches, because a vulnerability system tester declares a postive result, because they think it's Linix.....and current patches from VMware may not plug that hole!

10x,  hanccocka,
could you tell me where I can find patches for vcenter and srm software.
In the download patches section in vmware site there are patches only for esxi servers:
http://www.vmware.com/patchmgr/download.portal

10x for the links,
Just to ask you, I am reading that vmware has a product -vmware update manager that can be used for the purpose of the installing patches. Could you tell me if this product is only for esxi patches or it can be used also to install updates for vcenter and srm?
What version of vmware update manager I need to download and install now?

It updates Hosts and VMs, not vCenter or SRM.

Update Manger is included on the vSphere vCenter Server CDROM, e.g. 4.1
