Which DSLR to buy as a beginner?

I'm planning to move from P&S to DSLR and have shortlisted Canon 550D & Nikon D5100

But my friend suggested me to go for the Canon as the Nikon DSLR will not support most of the new lenses! So I'm bit confused :|
I'll use the camera for outdoor photography, landscape, family picture mainly, and rarely for video, low light photography. Which one does suite my needs ?

What are other brands and models of Flash transceivers?

I'm looking for transceivers, because I'm planning to fire more than 1 flash wirelessly. A have a Nikon D7000, and Sb910, Sb-80dx.

I know that Pocketwizards are one, and also another is the YN-RF603 transceivers. I want you to please list down other brands and models of transceivers, because i'm looking for cheap alternatives, and no, dont push me on PW and the RF-603, PW is very expensive, and RF-603, well, not good of a performance.

Music similar to this?

I listen to Electronic, Dubstep, Glitch Hob and that kind of thing… Especially when it still has beat but soft at the same time.

For example I like:

Savant- Redemption
Overwerk- Odyssey
Glitch Mob- Starve The Ego, Feed The Soul
Bonobo- Kiara
Nick Nikon- Dear Diary
Uppermost- Lovely Soul

Can you please suggest me more songs and artists like these. Thanks: D
