Lens recommendations for 70d video?

I have done small films before and am looking to get into DSLR. I have $2000 to spend for everything, and I've decided that the 70d is the best camera for my needs. This eats up half my budget though, before I get audio, a tripod, extra batteries and sd cards, and all the other little accessories I need. Lucky for me, I already have a 70-300 efs USM lens(http://www.bhphotovideo.com/c/product/397663-USA/Canon_0345B002_EF_70_300mm_f_4_5_6_IS.html) and a 17-85mm of the same type.(http://www.bhphotovideo.com/c/product/351548-USA/Canon_9517A002BA_EF_S_17_85mm_f_4_5_6_IS.html)

I am planning to do off camera audio so I'm not worried about them not being stm, but are they any good for video? And what other lenses should I consider?

Thanks in advance.
Added (1). The video camera I've used before I didn't own, and I'd like to stay in canon because I already have two lenses. I am looking for specific lens recommendations that fit within my budget.
