1) 2x 146GB + 4 x 600GB
2) 1  RAID1 using the 146GB drives, the other either a 3+1 RAID5 or a 3-disk RAID5 + a hot spare. Most likely a 4 disk RAID5
3) I have no idea if this is enough processor power.  That depends on whether the VMs are used to figure out pi to the gazillionth digit, or surfing the web, or somewhere in the middle.  Nobody can tell you if you have enough horsepower .. you have to establish some sort of requirements and explain what the systems are doing.

1. Install ESXi onto USB or SD card.

I would install ESXi onto a USB flash drive or SD card.

Here is the VMware KB on installing 4.1 on USB/SD:

As for disks, as fast and as many as you can afford. Hoiw much storage do you need?

2. RAID 10 for performance, or RAID 6.

3. Dual Processors, Quad Core processors is good for a start.

Memory is often the bottleneck, not CPU, so make sure you have enough memory.

I would ask for an upgrade to the processors for the E5-2609 does not support Hyper-Threading Technology.

I wouldn't buy two CPUs for just 3 VMs, one should be plenty since there are only 4 DIMMs on the BOM.

1) go for the hyper threading CPU, it i s good to go.
2) go for 16 GB ram , and depends on the VM ram sizing. Also make sure that the total VMs memory + 3GB should be equal to the total RAM ESXi.

Remaining things are ok.

with regards

A simplified explanation is that HT lets the same physical CPU do more work by doing more than one thread (a unit of work) at a time when the code you are running allows such things.  Most people see 10-15%, but don't expect for much more except in corner cases.

Personally, if you have to pay more than 20% more money to get a CPU that supports this vs. one that does not, then you are past the break-even point and it is a bad deal.  Conversely, if you can by another physical CPU for less than 20% more money, then that is a better deal.

Most CPUs are now Hyperthreading.
