This looks like a good plan. Especially the (unquoted above) idea of leaving space for the two LVM areas to grow into, depending on your future needs.
Just one minor nit... Swap on raid-1 is overkill. If the system gets an error reading or writing swap, it mostly just reboots. This is infrequent enough that rebooting is an acceptable response. The overhead of raid-1 isn't justified.
You may hope to gain some small speed advantage by doing swap on raid-0, but you can accomplish the same thing by allocating two separate swap partitions on two different disks. The system will know how to use them to its best advantage.
