I've been trying to figure out stat generation as well the last couple of days. I've made a Java program that will spit out a stat list if given a player's G, HR, AB, H, TB, SB, position, Arm Strength Fangraphs Scouting Report rating, Fangraphs Defensive Value, and FLD%.
It uses the following formulas:
TRJ, CON: Jag's method
PWR: Jag's scaling, averaging the stats from HR% and ISO so that players like Cecil Fielder and Joe Morgan can not be over or underpowered
RUN SPD: Some stuff with steals, which I thought was as good as anything else, though it probably needs refinement
ARM STR: The FG rating
FLD: Takes the average defensive value for a year, divides it by five, adds nine, and makes it an integer
E RES: Finds the best fit of a scaling list, which is different for SS, 3B, C, and 1B than for the other 5 positions. It might be flawed, it spit out C 10 for Andrelton Simmons, but that is what the stats seem to suggest.

I think looking at the defensive value and just spitting it out for everything is a bit shortsighted (Simmons among others.)
It's a good start though.
My Java program does not calculate abilities though, so I don't have any of those.

1. Is there a way to have the results of your Java formula wind up in a spread sheet?
I'm fairly sure, but putting it in a .txt works fine for me and I don't yet have the drive to find the other method. I've just been copying the data over into a spreadsheet from there.
2. I'm wondering if you just click and paste the stats or do you have to input all of them manually?
You put them in a .txt, separated by " | ", and the code reads those and puts the results on a different .txt.]/b]
3. How long is it taking you to do the stats for a 40 man roster? The reason for my streamlining the defensive abilities is due to the amount of time required to get a team done. It's taking me well over an hour to get a roster done, and once I have completed the spreadsheet, I still have to go into my game and make all those edits, which is another hour plus.
[b]I have no idea. It would probably take a while just for getting all the data, but once you had it you can just press the button once and it'll run through the whole set.
I think I mentioned that I don't have abilities yet. To get them would require a bunch more stats and a bunch more code. I'd rather not automate that.
If you put in a w/RISP and the program spits out "No RISP," that's still another column. I don't want like 40 of them.

A's hitters ratings are up, there are a few player with some missing RSPD, ASTR, FLD, AND ERR ratings though so if anyone has ideas for those guys when they look at them, feel free to contribute your own ratings.
