Not the one who play with, but still what
@Middleclaw said, watch the Season of Direwolf20 SSP that is according to the DIrewolf20 pack version you are going to play.
Dw20 1.7 = Season 7 I think.
I did start this way and every now and then when I have trouble with a specific mod, I watched his Spotlights( he has a spotlight for 90% of the mods that he uses in his packs) and consult the wiki.
If you are wanting to play FTB, once of the main things you need to be aware of is that is has a learning curve that requeires you to pass more time researching on internet then to play.
At least at the start...
For me thats one off the main ascpects what I enjoy playing Modded Minecraft.
So for me having someone to teach me, would take out fun for me and makes you not having the feeling of "wow I managed to get this working"
So if you start playing with someone, look for one with the same expirience as you so you can help each other but without spoilering to much.
Also Direwolf packs and the big other kitchen sink packs have so many ways to do stuff that if someone will "train" you, he will spoil you a lot of mods and not making you finish others until the end.
Why should you for example try logistic Pipes if you can start with AE2 also.
Just to give one example.
