I am a new woodworker trying to get started. I have an old craftsman table saw and I checked the run out on the blade with a dial indicator. It showed that it was .003 out from front of saw blade to back in relation to the miter slot. Is this good, bad or acceptable and should I try and correct this? Thanks in advance for any help.

IMO .003 is exceptable, go make some saw dust.

I wouldn't worry about it. It's woodworking not metal working. Most plates on sawblades are not going to be anywhere near perfect. That's well within tolerance. As they say "if it aint broke, don't fix it". "Or alternatively, if it aint broke, it hasn't been fixed enough"!
The acceptability is up to you. However, if you have additional runout due to other causes (arbor flange, etc.) then it might start to add up. The proof is in the pudding. If you are happy with your joints, then it shouldn't bother you.
In the event that there is interest in fixing... I am not sure if they make the PALS system for a Sears saw. It is a veryslick $20 solution to aligning the trunnions parallel to the miter slot. My Delta had .004" runout front to back and within 20 minutes I was able to reduct that to less than .001" with the help of the PALS system. I bought it from Woodcraft for $20 or so.
Thanks for all the input. I didnt feel that .003" out was very bad especially when I looked at it on a feeler guage. I just hear about all these seasoned workers talking about how accurate a saw needs to be and I wanted to check on mine.
Clean the blade washers. Generally there is buildup on them from rust or dust.
My personal favorite is using the Steel machined pulleys for the belts on the arbor and the motor shaft. Change them out and you'll do away with that slipping belt problem. If possible rewire the motor for 220 volt. you'll never regret that. Some TS by craftsman have only 120 volt motors so don't be disapointed if it is that way.
Shine up the table and have at it.
