Hi,
Here's some links to threads on warseer from earlier this year talking about forgeworld tau. I almost sprung for buying them in the summer after seeing a member there post a list of things to buy for a 1500 point list. It was the following:
Custodian (1 pack)
3 Wardens (1 pack)
2 Protectors (1 pack)
2 Emissary (1 pack)
6 Castellans (2 packs)
plus Kor'O + Aun'O
1495pts
cost: 60 pounds
Here's the link where this list was originally posted (it's on the second page toward the end of the discussion):

Here's the link where I posted about it and asked about how many manta / barracuda packs to buy (the consensus was two packs of each would be more than enough, but they're not included in the list above because apparently you can print out templates for small "ordnance" things like fighters and bombers. This was the recommended approach in the thread, also):

One more thread with links in the very last post from the user (horizon) that I was taking most of my tips from, linking to several other threads where he gave advice about
FW Tau:

Anyway, I hope this helps
. I was also very keen to figure out what the list would be before I bought it, so I could buy exactly what I needed (and not any extra). I didn't end up springing for it, but hopefully the research will help you
Edit: Now that I look at it, the list you posted is really similar to this! Which is great. The user giving most of the advice (horizon) also mentioned that protectors were a bit better than emissaries, so just having one of those in your list is probably a good idea
. Although since they come in packs of 2, you'd have one emissary left over, and one protectors left over, if you leave it as-is. In the list I posted above, I believe the only leftover ship is 1 warden (they come in packs of 4, if I'm remembering right, so you'd have 2 left over if you leave it as-is).
