For the LFG to work you have to put down a time (ish). Like "I'll be on in one hour (start time 9pm edt)". Or you can say "I'll be on thursday 3/1 at 9pm edt". Or at least say "I am normally on week nights starting at 9pm edt".
It may also help to say where you want to go or what quest you want help with. Like "lets go to the dragon isles and adventure" or "looking for help with Trent's call to me to get the kabold stick".
Generally, as far as making your char stronger you need better gear. Start building credit at the Saddlebag, and/or shop around at some of the guilds. Gear can make a big difference for fighter types. I would start a craft, probably alchemy, so you can make your own heal potions and some other neat things. It will give you more demesion and some thing to do and save you trues.
If you can even find one person who has a lowish level like yours and meet with them regularly to do the static quests or look for flags..will help you alot.
