venting options

I'm redoing my bathroom in a big way. I've cut out much of the four inch cast iron soil stack and have coupled in pvc. There was a 2 inch branch that hooked into the main vertical soil stack up higher that then went down into the basement and was capped (unused) I'm wondering if I should replace it with a pvc version just to have some venting options later if needed. The other question involves where the sink, tub, and 2 toilet drains meet up with the main vertical stack. Does it matter if the toilet drain comes in above the sink drain? That's how the original was for 80 years.

It's a lot easier to leave a capped vent to teh basement now than to add one later, I'd leave it there even though it hasn't been used for 80 years. Not sure about your vent order, but I would think you wouldn't want your sink drain to flow down your toilet vent stack (maybe I misunderstood...)
