newcomer having questions

By TheSon, in Deathwatch

So hi, I'm a WFRP player who may be interested in beginning in Warhammer 40K, but I had some questions first:

1.Do the games DW, DH, RT and black crusade use the same rules and are usable with each other?

2.Do DW use the same rules (roughly) that WFRP ?

3.Is there visual elements in this game like in WFRP (punchboard, action cards, plastic base and tokens)?

1. Yes, but the pre-made adventures in dark heresy and rogue trader are created for characters significantly less powerful than deathwatch marines.

2. Possibly, but the two universes are completely seperate as the creater of the IP, Games Workshop, has stated numerous times.

3. No, this is a true roleplaying game not a clix game. While it is possible to use character miniatures (specifically from the warhammer 40K minis) with maps or what not similar to Dungeons and Dragons characters and maps it is not necissary.
