DIY Speaker Project PAD

I'm about as green as it gets, so I hope this isn't a stupid question.  I'm super-excited to give DIY a try, so I opened my Speedster kit today, and ran into a question right off the bat.  It looks like the crossover specifies a 10 Ohm resistor, but my package came with two 100 Ohm resistors (the other two are 8.2 Ohms).  Is this a problem?
While I'm asking questions, I also wondered about solid wood baffles.  I've noticed a few of these on DIY boards, but I've always been advised to allow for movement in solid wood (floating panels, breadboard ends, z-clips, etc.).  Are there any structural concerns with gluing a solid-wood baffle to a plywood box?

Thanks in advance for your advice!

Got the components figured out  I also decided to go with a ply or MDF front panel, so I'm not worried about that.

I did have another question though: I have a couple Audyn Q4 caps and a couple Bennic XPP caps, all with the same value--does it matter which goes where?

Use the Q4 on the tweeter and the Bennic on the woofer.
