I'd inspect the small chainring first for tooth wear. The OP may think it's skipping cogs when it may be skipping on the ring, might be hard to tell the difference. New chain and new cogs should match well, but I've gotten skipping with new chain on old cogs, so maybe this time it's new chain on old ring. If small ring checks out, look at the other stuff.
