Help! I don't know what I'm doing! (The wiki is killing me :P)

The wiki updates with new informaiton every night I come home from work so I cannot keep track and my invetory i perpetually stuffed. Can someone help me out by 'guiding me on useful things to keep and use and what the 'top end' things are that I can aim for?

I currently have Knightly Sword and Fine Steel - Aiming for Katana when I find chalk.
Armorwise I'm using 2x Iron Thorns, Fine Alum Helm, Serpentine and Winged Alum Boots.

I have been storing things like Tinker, Grinder, Stills and Alchemy boxes in the hope I may be able to use them - Is this foolish? I am keeping some useful potions such as Volt/Infern/Borean etc for boss fights and Invis/Rejuv/Teleport for escapes. I keep a small stock of Merlot for emergencies and 3 stacks slots for good cheeses.

The rest of my space is bloody ores, powders, gems and tinker bits incase I could use them sometime (I dunno though)

So yeah, basically I would really like someone to give me a clear idea of what I should be aiming for, what I'll need to keep and what I should sell (I mean 17 Platinum as I was hoping for Platinum swords )

BTW - I'm on Level 4, A level 10 character with my 3rd run (I've had runs since but was able to recover this from 1.02) - I'm playing Dual Wield, Viking Magic, Assassin, Smith, and some other physical based things.

 

ok so do you really have to spam these?

 

Wow holy crap I promise you this is the work of the devil. Not me >.<

 

Oh god - Monster Zoo

 

I find the only potions were keeping are Rejuv, Regen, HP, Mana, Steeling, Invis, Purity. The other ones really just add resist/dmg, so just use them as you need them for bosses and stuff. I've found Smithing to be pretty worthless minus the two rings that you can make(one for mage, one for melee). Usually by the time you have the mats or have leveled smithing high enough to make stuff, you already have better stuff.

I was once in your boat with really full inventory, i just started selling everything but food/booze and the potions i listed above. I Keep Nightcap mushrooms as well.

EDIT: For reference, i've played 25+ hrs and have made it to(and died) Dredmor.
