Sorry about a late response, but yes: VIP is permanent (for life). $15 for VIP, $30 for Gold Member. Gold Member gets a bit more (well worth it!), but VIP is also a great way to start.
Anyway, no: we don't have anything to do with Orange Cosmos (as they are DEAD). We are Catalyst Gaming, a new community in which adopted OC's gamemode, OCRP.
And lastly: VIP/Gold Member is permanent on ALL servers.
Thank you for thinking about donating! We appreciate any donation, no matter from whom.
