are high miles ok?
well 124 is high, but theres no reason you can't mod it and beat on it if its been well taken care of.
There are plenty of people on ls1tech that beat the hell out of their cars with well over 100k on the clock and they run just fine

I wouldn't "beat' on it. 
We break our cars with lower miles when we start to add hp.
The LS1 will behave better and is more reliable than the older v-8's (LT1,ets) with high miles. I still would buy the car and do your stuff, but you'll have to replace or better yet UPGRADE the parts that break just like lower miles cars, but on a more rapid scale because the old bones have more fatique.
125k miles isn't high, but you should keep a lil' money handy when you kick it like a stray dog.

Almost 140k on mine. It runs great, no problems to speak of. I took the car to E town on Wednesday to baseline it and it trapped 104 or 105 on every pass bone stock. Im considering a Cartek heads and cam package on the stock shortblock. Miles are only a number. Id rather have a car with 200k highway miles that was maintained properly than a 20k mile car that was beat to hell and had the oil changed twice. As long as the car was cared for I would not be scared of miles.

over 185k on my 98z.
no joke, it used to be an oklahoma highway patrol car.
(so it's not exactly a z28)
I think the coils could be replaced,
there's some minor electrical gremlins,
but other than that she's still nasty.

I pray that my Z can make it to 185...
My Z just rolled 20k, and seems to be taking my abuse well (I am still waiting to see how it handles the bottle
). We have had really good luck with our Mitsubishi's though,
The 'beater' Eclipse that I drive every day has 260k on it and still gets 30 mpg without blowing any smoke or leaking problems. Cheap and VERY easy to maintain for me.
The 'good' Eclipse that I built for the wife has @175k and is still trucking, and then we have our 'Family Beater Ride'. That car, is a Nissan 200sx which is still pooting around every day with a little over 317k on it.
(this car is so damn ugly that when we park next to people at restaurants and stuff they will actually come OUT of the place and move their car so as not to be parked next to it... )No matter what kind of car you get, If you got the TIME, the TOOLS, and the PATIENCE then you can keep it rolling along untill you get sick of them. What matters more to me, is how much the high mileage cars $$$ to maintain.

Chevy hp has a 99 z28 they are using a 150 shot. and the car hasn't used any oil. so i think you will be fine with a 100 shot. i have a 98 with 84000 and using a hundred shot this summer. just don't use platum plugs get some ngk 6s.
I sold a 94Z28 to a friend that was still going strong with 230k on it. But then he found a big rock wall and that finished the car off. I know it's not an LS1, but they are supposed to hold up better, so that says alot.
