You will be perfectly fine in 340 Creation gear or even 330; a lot of people first started clearing V1S in the 320 crafted gear, or even the 310 Verity gear or 320 Omega NM gear. So your Creation gear will be more than enough for it. Don’t worry about that.

If there aren’t any learning parties currently up in PF, don’t hesitate to make your own. If you just want to learn and don’t care about the number of coffers you receive upon a clear, a lot of veterans that have already cleared for the week won’t mind joining in on the PF and helping you out, myself included. I don’t know how fast RF queues are for V1S, because I’ve never queued into it that way before; it’s always been as a pre-made PF.
