Black Hole

Slightly long......to give a little background.
I bought my 01 Sport last Wednesday from a private individual.
The car had the airbag light on when I test drove the car, and it's still on as of right now. 50 miles after leaving the guys house, I had a CEL on Thursday night. I disconnected the battery and it disappeared for the moment.
150 miles and 5 days later, the CEL reappeared. P0171 and P0174 were the codes according to Autozone, but the guy didn't clear the code and I still have the light.
101,400 miles on the car.
Granted I haven't owned the car for a full week yet, but it doesn't appear to have any issues with starting, idling, or driving. I did notice that it idled at 1200 rpm on one startup until driven and a couple of other times it felt a little rough when idling down at 600 or 700 rpm, but it wasn't drastic and a "normal" idle on the Wrangler I just sold was worse.
One other thing....on a cold start first thing in the morning, it does feel like the transmission doesn't want to shift out of first....revving to 4k or 4500 rpm and shifting when I get out of the gas a little. However, I live at the bottom of 2 hills, so I'm almost always going up hill with maybe 30-45% throttle when it does this and it's been slightly cooler for the last week in the high 40's-low 60's in the mornings. It seems to go away after the first gear change and it drives normally the rest of the way to work. I park in a parking garage at work so I don't really notice it when I'm on the way home. I guess I think it should shift just a little earlier given the throttle position. Transmission doesn't have any other issues though....shifts smooth at part or full throttle.
Since I'm new to the car, here is what I know.....I'm unsure if the timing belt has been changed.....a couple of the wiring loom clips on the sides of the engine are broken which makes me think that it may have been done (and the previous owner thought the same, but he may have just been trying to sell the car), but the previous owner bought the vehicle with just under 80k and he didn't have it replaced. Previous owner put just over 20k miles on the car in a little over 2 years. He had the transmission flushed, added a K&N airfilter, replaced the fuel filter, had the rear axle pinion seal replaced, topped off the diff fluid at the same time, control arm bushings replaced, 4 wheel alignment done about 15k miles ago, as well as regular maintenance. She supposedly uses a little oil.
I've read a little bit on here and found the most common answer is to replace the MAF with the 04-05 Saturn L-series 3.0 MAF. I also plan to change the plugs as the previous owner thought they were original.
Am I on the right path? I've had bad luck with attempting to "clean" MAF's in the past, but I'd hate to drop $75 if I should just try cleaning it or start somewhere else.
Thanks in advance.
Matt.
