>1) He didn't like 2Pac because he felt he was a studio thug but
>agreed to record with him as a means of advancing his career.

This is verified. Pac was going to record with Shawn the night he got shot. He knew Shawn was just trying to use him which is why he charged him $7000 cash for the verse. Jimmy Henchman, who was Little Shawn's manager, kept calling Pac the night of to make sure he came to the studio. Pac wouldn't show up unless the cash was there, which Henchman assured him it was. You know what happened next.

>2) He was hanging around Jay-Z before he blew up and Jay used
>Shawn's car in his video.

Have no reason to doubt this. If you look at the video for "I Can't Get With That" (1994) at the 3:21 mark you see Shawn sitting on the hood of his car with a bottle of champagne in his hand:

Also, when Shawn got out of jail Damon Dash hired him. Shawn had this to say about Jay and Dame:

"Jay forgets about people; Damon doesn’t,” says the former rapper Little Shawn, who now works for Dash under the name Shawn Pen. “When I got put away for drugs seven years ago, I was better friends with Jay than with Damon. I never heard from Jay that whole time. Damon stayed in touch. The guy’s not a letter writer, but he got word to me. He gave me a shout-out on BET. Do you know what that means to a guy in jail?"

>3) How the whole Biggie relationship formed and that he was cool
>with Un before rap.

Don't know how to verify this but Biggie did shout him out on "Party & Bullshit" and was in the "Dom Perignon" video. Seemed they were cool. Pretty believable.

>4) He was making records in the '80s with Hitman Howie Tee.

Verified. Little Shawn - Heartbreak Hotel (1987). Produced by Hitman Howie Tee and Chubb Rock:

>5) The fact that Ja Rule basically jacked his entire "Dom Perignon"
>style and used it to blow up. I mean look at this shit:
>http://www.youtube.com/watch?v=Z3Yutm3qK_0. It's like Ja watched
>this and said "I'm gonna do this on every song".

That's just my opinion but I think it's obvious.

>6) 50 Cent looking up to him for being a street cat but not rapping
>about it.

I remember around 2004 there being rumors about 50 signing Shawn to G Unit. Shawn confirms it here but who knows if it's true.
