Backlash is mostly just something to be aware of, it doesn't really affect anything. At least not anything I can think of at the moment. My lathe has a full turn of backlash in the cross slide. About shot, but it can produce work within a few tenths (.003mm).
What you are describing sounds more like spring in the tooling to me. Perfectly normal. Get used to making two or three "spring" passes and you'll be fine.
on edit: I just thought of one thing about backlash- it's annoying! Threading requires pulling out the tool bit for the return trip. Shouldn't have to turn the handle much, but I have to unwind mine a full turn before it starts to move. So it's a time wasting annoyance.
