Warframe goals

Level to 30 -> Stuff to start grinding up
Mag -> Rhino -> Excalibur -> Valkyr -> Nyx -> Ember/Oberon
Braton -> Strun -> Dread -> Attica -> Vectis -> Drakgoon -> Soma -> Latron -> Boltor (Mk-1 Braton as last resort) (Tiberon?)
Dex-Furis -> Lex -> Seer -> Bolto -> Despair -> Twin Gremlin -> Akbolto (Aklato as last resort)
Cronus -> Furax -> Glaive -> Dual Zoren -> Jaw Sword -> Ether Reaper -> Scindo -> Orthos (Dark Sword, Skana as last resort)
Carrier -> Dethcube -> Kubrow (Work towards 300 Oxium for Helios)

Build List (current blueprints):
Saryn (Chassis only so far) (Grind Sedna Boss)
Banshee (Chassis only so far) (Clan only?)
Zephyr (cosmetic helmet only so far) (Clan only?)
Hydroid (cosmetic helmet only so far) (Grind Vay Hek (Jesus christ you have to do what to get to this guy?))
Loki Prime (Chassis Only)
Vauban (need one more)
Loki (Cosmetic Helmet only)
Banshee (Cosmetic Helmet only)
Volt (Cosmetic Helmet only)
Mag Cosmetic Helmet (So ugly....)
Detron (need Cells)
Kronen (Need Argon Crystals)

Would-likes:
Orikin Reactors for my frames
I need lots of Orokin Cells... (Saturn Dark Sector, Sargas Ruk, Void/Derelict Defense/Survival, Saturn Survival/Defense, Saturn Aegaeon Exterminate)

Stance Types:
Done: Fists (Furax), Scythe (Ether Reaper)
Hammer (Magistar is best option, else Fragor, or Jat Kittag from the Clan)
Nikanas (Even with a clan, getting this thing will be a nightmare. 3 Argon crystals?)
Polearms (Orthos, maybe a Serro from the clan?)
Machetes (Nami Solo, Kama, or clan Prova)
Dual Daggers (Fang is really the only option)

Build Em-bettering (Mods to grind for):
Mag should be focused on spamming powers: Need mods that increase power effect/efficiency/range. Also a golden potato.
Rhino just needs boring em-brickshithouse-ening mods.
Excalibur....uh....just Stuff In General, for experimentation
Valkyr: survivability, power duration, melee aura
Nyx: Survivability and power spam, cast time reduction?

RP Bullshit
Mag/Valkyr would be Katina, so shortrange power, shottie, Punching, magnum pistol
Rhino will be Russel, with the most Generic of weapons, and built for being a Castle.
Excalibur, frankly I bought it because I had Plat and it was cheap. I kinda have a Mister Bushido thing in my head but the single horn kinda ruins it for me.
Ember???? (Laika?)
Nyx????
Oberon????

Part of my problem is that I can't think of any 'must-have' guns, mods or Frames I really want, so I'm going by what the game drops or I happen to see in the wiki.
