Another alternative to Wiz 3 is to take Beast Tamer as your Natural Explorer option at Ranger 1 for Find Familiar and then Circle of Land Druid 3 and take Underdark for Web.
Note that both your Beast Master companion and your Wildshape get stronger as you level those specific classes. If you take a bunch of extra Ranger levels, your companion will be more capable in combat, but your Wildshape will just make you weaker when you use it. Similarly, if you take a bunch of Druid, your Wildshape will be okay, but your companion will die to a hard glance and a stiff wind. If you do neither like you say, neither your companion or Wildshape will have much combat utility, but at least you can look spidery outside of combat.
