That rod will work. I don't know as I'd go any shorter, though I might consider going "lighter" (as far as rod weight goes). A 6-8' graphite rod with large guides & tip eye will make a good "bobber" fishing outfit, paired with a wide spool reel.
You don't really want a short rod, when using a bobber, unless you're fishing real close to it. The longer rod helps take up the slack & makes a stouter hookset from a distance ... without having to use your arms as much. Longer rods also allow you to use a fixed bobber (spring or clip, line attachment style) and cast/fish it as deep as the length of the rod. Even using a slipfloat, a longer rod still takes up the slack & sets the hook faster/easier.
Brand & action are personal preferences, sometimes dictated by price, looks, recommendations from other users, and/or personal experience. But, whatever brand/action you choose ... be sure and pair it up with a reel that balances well with the rod. You don't want too small a reel, which will make the rod "tip heavy" .. and strain your wrist to hold/cast it. You also don't want too large a reel, which will make the rod "butt heavy" ... and strain your arm/shoulder to hold/cast it. A good rod/reel combo will balance on your outstretched finger, when laid across your finger at the front edge of the handle.
Many 6-8' rods come in 2pc ... so "packing" them shouldn't be much of a factor.
