I'd get new everything, including brakes appropriate to the group set you decide on that is in your budget.
I know nothing about Klein's though. Try to coach your sentimentalism with the fact you won't make it much lighter than it already is and that you'll spend what might be a really nice new bike.
Might be a little less if you intend to mix and match deals you find here and there. But that seems a disservice to the bike. But maybe good for honing your DIY skills. It did do a lot for me when I built up my 1991 Paramount from a frame and fork. Put all new 105 5800 11 speed on it.
Almost did the same to my Raleigh, then realized it really wouldn't be that much a different bike. So I got a new bike and now wonder why I waited so long to get a really brand new bike. I don't ride my Paramount much any more. The new bike is just too fun.
Agreed there is a lot of sentimentalism in this rebuild; along with just the desire to learn how to build a bike up from the frame.
It also will make for a great bike to keep on my trainer year round. Currently I just have 1 real road bike so once spring hits; I take it off the Wahoo. Would be nice to have the ability to have a bike ready for full time trainer status for rainy/crazy hot days.
