You can gain a lot of hps, mana and mana regen from gear by using the new player made jewelry for ear x 2, finger x 2, wrist x 2, face and neck. For your level you'd want Velium Trio. For a total summary of how it works and what all is available, kyroskane has this spreadsheet
http://www.editgrid.com/user/kyroskrane/Jewelcrafting and this calculator
http://www.kyros.info/Tradeskills/JC-Calc/. I prefer the spreadsheet, my roommate prefers the calculator /shrug. (Thanks to kyroskane for making these up, invaluable for explaining the new system)
I would suggest using 2 of the slots for Mana regen from square cut rubies (each giving mana regen 6). All slots have square cut opal (90 hps +/-) and square cut emerald (90 mana +/-). For the slot 11 aug use the best of what you can afford of the following 3 possibilities Prestidigitase (90 hps/mana/end), Harmonagate (120 hps/mana/end), or the big one (also the most expensive) Taafeite (150 hps/mana/end). These also give stats, saves and AC depending on which cut you use. The numbers listed here are the max for velium, they differ depending on level and setting in which they're inserted.
If you know a jeweler, great. However, if not, the setting and the gems are not that expensive (until you get to harms or taafs). Another nice thing about new jewelry is that when you outgrow the recommended level you can take off the gem augs and upgrade to the next setting (in your case palladium, then dwerium), making the gem augs a one time investment. Due to the scarcity of scale ore, palladium is more expensive on average than the higher dwerium.
Hope this helps, I've made a ton of these for my alts, my roommate's alts, and several friends returning to the game after long breaks. There's a lot of excitement when they see their hps/mana skyrocket in an hour by waiting for me to make them (and full sets of the Energeiac appropriate for level).
