@MdaG: I'd suggest that first of all you sacrifice stuff until you're at "very pleased", bless your potions of water, dip the scroll of uncursing into one of them and uncurse all the cursed items in your inventory. Then eat four morgia roots, put the moss of mareillon in your toolslot, press 'u' twice and put it back in your pack. If you know where to get more of those two herbs, you could go and get some more first (as you don't have the herbalism skill, all the herbs you get will be cursed and need to be uncursed before they do any good).
One thing you definitely need to do is get rid of Moonsickle, because that's where you got your corruption from and you'll get corrupted even further if you continue to carry it around with you. Since you're lawful, I'd suggest that you sacrifice it for the extra lawful boost.
You're right, your equipment isn't all that great, but if you spend some time in a place where monsters respawn quickly, like the cavernous level of the puppy cave or the big room, you should find something better. Only if you're sure you can handle it, though; both can easily get crowded by summoners. You could also try blessing your potions of invisibility and making a quick dash through the small cave and to the unremarkable dungeon (bless the scroll of magic mapping if necessary, go to the cave, drink a potion of invisibility BEFORE entering it, read the scroll, go on coward, try to avoid the monsters and just go for the stairs; don't bother about the blanket). You should try to find a decent shield for additional protection as well. And obviously it's a waste for an archer not to have a missile weapon in his pack. Go hunt a few kobolds or barbarians...
However, there is one you can do now: wear your hooded cloak and your uncursed gauntlets (that's an extra +1 +3 DV/PV bonus). The amulet of order won't get you any further than L, so you might as well exchange it for the amulet of speed.
Anyway, don't try to go deeper into the caverns of chaos too soon, or you'll probably get killed.
