I have an absurd schedule, so my Thursdays are free, mostly. I usually sleep until noon, but whatever. I have a level 3 and a level 5 that can help, though without knowing exactly what time zone you're in, I can't guess when you can catch me on.

Might be a good idea to establish a guild roster at this point. Corwin, you might take our characters and place them into the original post, so that a list can easily be found. I wouldn't worry about keeping up with levels, races, or classes, as that's easily found in game; just a list of which character belongs to who will make it easier to tell whose on. Especially for you, since you can't remember your own characters' names.
Peter covered most of the important stuff, but here's a few things that will help a little.
1 - Fortification - Wear it. Early on you can do without, as light has minimal effect. Around 6-7 you want to find or steal a Moderate Fortification item. If you're extremely lucky, you might find one at ML4. As early as 9, you can have Heavy Fortification, which is very important. Fortification protects you from critical hits. Even in the early game, you'll see ogres in level 2 and 3 quests slam out 20-30hp of damage a hit, which is difficult for the low level healing abilities of the clerics and bards to keep up.
2 - Toughness feat - In PnP, the toughness feat is rather useless. In DDO, it gives 22 hp at level 20, and opens up both racial and class toughness enhancements. Each race has, at least, 2 enhancements for 10hp each. That means 42hp at the bare minimum. Some classes also have these enhancements, which stack with the racial ones.
A Warforged or Dwarf will have up to 4 racial toughness enhancements, Humans 3, and Half-Elves can either have 3 or 5, depending on their Dilettante feat. Fighters, Barbarians, Paladins, and Favored Souls all have class toughness enhancements, up to 4 tiers.
There is also a few items with the Toughness feat attached, these are very good to have. In particular, the Necro 4 pack has a helm called Minos Legens, which is ML11, and has Toughness and Heavy fortification all on one item. There's not a whole lot better in that slot for many builds.
3 - False Life - Items with the 'False Life' enchantment give additional hp; 5, 10, 20, 30, and 40.
With a Greater False Life, Toughness, and +6 CON item you can gain an additional 110hp over your base, regardless of feats or stats. I consider this basic gear, something you should aspire to have by 15 or so.
4 - Need cash? Sell essences. Cannith Crafting may be in your future, but for now, I'd suggest selling off those greater essences for plat to buy mire useful-to-you things. Notably, I try to keep at least a stack of 100 Cure Serious Wounds pots around, as well as pots for neutralize poison, disease removal, blindness removal, and lesser restoration. On those who can't cast it, carry resist energy pots. You can gather up decent stocks of these from breaking crates, but selling essences and buying them is faster and more reliable.
5 - Don't buy Drow. Friends don't let friends buy Drow from the DDO store. 400 favor is easy to get, real money means dealing with management.
