Brand new to costuming, unfortunately. So I am creating a thread to post what I have been able to do and you can help give me advice and get me started

I have done a ton of research and haunted these boards for the past few months before I started my build.
I saw from one of Ang's posts that she has used SyFabrics for her fabric, so I have a couple of feet of fabric from them in the red velvet. They were out of the burgundy so I haven't acquired that.
I have also already purchased 2 of the little mini ACs that people suggested on the helmet cooling thread on these boards.
That, so far, is the extent of what I have. I have a friend who likes crafting tools and weapons so I can probably manage a forcepike without too much extent. But I have never built a costume before and really don't even know where to start.
Any tips for what I want to pay attention to when trying to sew the robes?
As for the helmet, I am so lost. I can't vacuform and I don't have any skill with making such things. I looked into what helmets are out there and TPE was recommended many times but I am not sure that I can dip into the funds for a TPE helmet without ruining my chances of making to Celebration Anaheim.
*sobs into his hands* I need a Jawa or two to go out there and strip me a few good parts.
