Proper network setup - R410 and md3200i

Two part question (well, maybe three):

What I have - 2 Dell R410 Servers, 1 Dell md3200i and 1 QNAP TS-1279-RP
On the R410s, there are two onboard NIC ports and a 4 port add on card, the QNAP has 4 NIC ports
The R410s are running ESXi 5.5 with the latest firmware, same for md3200i (as far as firmware)
The md3200i has 12 15K 600GB hard drives in RAID 10
The QNAP has 10 7200 2TB drives in RAID10 and 2 460GB Samsung EVO SSD (currently mirrored, however have had them not in RAID and striped for testing)
The devices communicate via two HP ProCurve v1910 24G switches - one handles LAN traffic and the other iSCSI traffic

My questions primarily involve getting the best performance by having the correct networking set-up - and thus my questions are primarily targeted at the phsyical switches and network setup in VMWare, but, as I'm dealing with multiple brands and devices - makes tying it altogether a little more challenging.

I have questions about how the ProCurve handles link aggregation and how that relates to tagging and vLANS (and trunking). It's all very confusing (to me)

Let me take a simple example. On the QNAP, it allows aggregating two ports - on their interface they refer to it as "port trunking" - the two ports are aggregated and the interface protocol is IEEE 802.3ad. These ports I'm using for iSCSI traffic from the QNAP. They go into two ports on the iSCSI switch and those two ports are assigned to a VLAN on the same subnet. In addition, I have one port each on the switch going to a port on each host, also on the same subnet and a VMKernal entry on the hosts in VMWare set to the same subnet - so, they all communicate and work properly. What I dont understand is the proper way to group those 4 ports together on the physical switch. Or if I just need to aggregate the ports going to and from the QNAP. But it doesn't seem as simple as aggregating - and I can't figure how trunking (LCAP) and tagging play into the mix. Then the connections going to the host, I realize I'm limited by the single connection, however the way I have it setup, the other ports used for management, vMotion, iSCSI traffic to the md3200i as well as LAN traffic (for NFS shares on the QNAP)

The question is similar for the md3200i. Each port on the md3200i I have on it's on subnet. Currently I'm only using 4 of the 8 (two from each module) and they are grouped via VLAN on the switch to 4 ports (two from each host) on the hosts. Again, on the switch I only have these assigned to VLANS, I don't have them aggregated / trunked. And I probably should to maximize my iSCSI throughput. I just don't know the best way to do this.

Lastly, since I have 4 ports on the md3200i I'm not using, is it smarter to put those 4 on the same subnet of the 4 that I'm using so improve throughput? Or is it pointless since I'm limited by the two on the hosts? And if I do do this, do I tie the VMWare kernel virtual ports to the physical NIC associated with that subnet?

This all started because we have these two SSDs in the QNAP and have them there for a r/w performance increase, however no matter what I do, I max out and around 110Mbits r/w via crystal disk mark - whether it's the md3200i RAID10 ,the QNAP RAID 10 or the QNAP SSDs - which makes me suspect it's my "pipe" that's the problem.

To anyone that took the time to read all that, I thank you! It's helpful to write it all out for my understanding and also hopefully to get some assistance. I'm going to post this in spiceworks, dell, HP and QNAP forums.
