Never, ever EVER co-sign a loan for anyone. If the banks consider the person too much of a risk, then you putting yourself on the line for them is just lunacy. If you were nice enough to co-sign a car loan to allow your adult child to have a vehicle that she needs for work and then she paid late or wasn't paying at all, which you probably knew was going to happen... that's kind of a facepunch right there. (sorry)
Repossess the car, sell it or turn it into the place it was purchased and pay off the remainder if the loan is upside down. Refinance it if you have to so you can take possession of it to get rid of that loan.
You need to start practicing some tough love on your daughter and separate yourself from this fiasco ASAP. DO NOT PURCHASE TIRES for her as a christmas present either - the whole car should be gone, and she can take a bus or bum rides from friends since she apparently isn't able to pay for a car herself (or maybe she is, she just thought it would be easier on her if you took over so she doesn't have to think about it). Your daughter's taken serious advantage of you and if she really doesn't deserve a present - christmas or otherwise - from you again unless she makes this right (paying YOU back for the money you're out on HER car). You should not loan any more money to her - ever.
And I'll just say that the fact that she is taking advantage of you, has either no/lousy credit so mom helped buy her car, and instead of being grateful and building up her credit by being responsible, she is neglecting the vehicle and behind on the payments - forcing mom to come to her rescue again... PLEASE FOR THE LOVE OF PETE STOP DOING THIS! She will never learn that her actions have serious consequences if you keep swooping in and fixing things for her.
I get that she's your kid and you love her, but family members taking advantage is a huge sore spot to me - you are teaching her to be irresponsible and dependent on someone else to take care of her, and she has no respect for what things cost or taking care of them to make them last. (and yes, I've personally had that happen in my own family, which is why I feel so strongly about this - all done out of love - but the crippled personalities and the horrible things I've seen as this progresses... just don't keep going down that road for both your sakes!)
As far as the rest...
You have a great monthly income and a good chunk of change in your 401K, so you could dig out of that debt and build up a decent nest egg pretty fast if you buckled down on some of the spending leaks.
Your grocery bill is crazy high for one person - should be close to half that even if you're buying organic. Your phone is crazy high (see the phone superthread for suggestions) but I'd do a buyout if you are in a contract and go to something like Republic or the like for MUCH cheaper. If you work from home, how are you spending $300 a month on gas?
I'd focus on reducing those and clear your debts in the first half of 2014, and then take a good look at upping or even maxing your 401K contributions and take a good look at what you're invested in (low cost index funds are the gold standard).
If you want to buy a house, I'd suggest you figure out what your price range is (and it should be less house than you would be approved for if you want to keep more of your money for yourself), and then set the goal of saving the 20% minimum (to not pay PMI) of that before purchase. If you can get that figured out, then that tells you how much to save and how much to send into your 401K. And when you are nearing the 20% house savings, then start looking.
Good luck! You are actually in decent shape to still do an early retirement - maybe not in the next 5 years, but you could push those expenses down and up your savings and be done in 10 years easy.
