It makes sense to me that I could install vinyl siding over existing T1-11 plywood siding (no sheathing-the siding is the sheathing, with builders paper under it), but would I put a new layer of building paper over the plywood before installing the vinyl?

Also, the existing siding has vertical 1x3 "battens" at every stud. Could the vinyl be installed over this, leaving about a 3/4" gap between the vinyl and plywood between the strips?

I would remove the battens as they will cause lay problems with the siding. You want a solid stratum to attach your siding.

Thanks. What about the builders paper?

I prefer Tyvek, but others advocate builder's paper. Probably a toss up, but added protection for your underlayment is needed.

New foam backed vinyl siding is superior any other siding material no maintanance, very good insulation, we use ***** with 1,5 inch insulation and a R value of 5,3, highest on the market will be qualifying for tax credit this year $1500. NoAds.com As for Tyvek bake paper does not drain any moisture behind it therefor will cause mold and moisture damage to your walls. Use raindrop by green guard not much more in price but a lifetime of drainage for any water coming behind your siding. good luck
