Setting up my first grow tent ---- looking for advice

I'm setting up my first grow tent and am looking to this amazing community for advice.

Tent: Secret Jardin Dark Room II Pro 60 - 24 x 24 x 64 Inches ----135$

Light: iPower 400 Wt MH/HPS Kit (includes ballast,timer,dimmer) --- 185$

Ventilation:4'' inline fan w/ carbon scrubber (exhaust) --- 90$

What else would I need to construct the grow-tent itself? I think I would need a thermometer,humidity probe as well? Also what tubing is typically used? Do I need an intake fan as well?

----After I square away what grow tent I'm buying I'll be posting more about actually growing!

EDIT: Several people have brought up concerns about heat and that the 400 wt bulb may be at the top range. The tent size is fixed, but do people have comments about what bulb would be optimal for this tent setup?
