VMWare Lab Plans (Vet my Setup)

Am planning to do a lab for both production stuff at my home, and a lab to practice towards my certification, and would just like someone to vet this setup, and give any suggestions they may have towards improving it.  90% of it's already in and setup, the rest is in transit, with the only thing not purchased yet being the 2nd gigabit switch.

Note that I am a systems administrator for a enterprise class hosting company, am quite familiar with Linux and Windows (definitely more of a Linux slant), and have used VMWare Workstation for personal stuff, but am otherwise new to that corner of the industry.  If anyone has any good, solid suggestions for VCenter5 books, I'd appreciate that also.

My house is also properly networked (Cat6 drops in every room w/HTPCs, desktops, and other sundry items like network BluRay players), I have a large, very cool temperature basement with under the stairs built out into an enclosed space for all the gear (a central storage server/domain controller plus three HTPCs live here, all the network drops here for the house, and an air conditioning duct outlet), as well as a self-built 24U four-post server rack, and 2 dedicated 20A drops for power there.

For iSCSI, I'm using the free version of Starwind for iSCSI targets, which also allows 128GB of HA storage.  So, presenting a primary iSCSI target off my existing domain controller for the house, and also two HA nodes, running on SSDs: one in the domain controller, and one on the primary HTPC for the house.

Dell PowerEdge 2950 III, w/4 Gigabit NICs each (2 onboard + 1 dual Intel Pro/1000), diskless (USB boot), and 16GB of RAM each

Whitebox, KGPE-D16 w/dual 6128s, 64GB of RAM, 4 GB NICs (2 onboard + 1 dual Intel Pro/1000), diskless

ESXi Host Total: 32 cores, 96GB of RAM, 12 GB NICs

Starwind running on the domain controller for the house, w/dedicated 2TB sata (non-HA storage) + dedicated 128GB SSD (HA storage, node 1).  This is in addition to a 9650se w/8x2TB in RAID6 for use as the house NAS (movies, etc).  3 Gigabit NICs (1 onboard, 1 dual Intel Pro/1000)

Starwind running on the primary HTPC for the house w/dedicated 128GB SSD (HA storage, Node 2).  3 Gigabit NICs (1 onboard, 1 dual Intel Pro/1000)

All CAT6, tied to 2 24 port gigabit managed Layer 2 switches (went with 2 x 24 ports, instead of a single 48 port so I'd have the advantages of a multi-switch network).  Have a Netgear WNR3500L w/DD-WRT as my gateway and a Juniper SSG5 Firewall also.

2 x 20Amp dedicated drops (each on their own breaker), and a rack mount 3000VA battery backup.
