I'm Just trying to get a better understanding about the I would really like it if someone could tell me the movement of it and how tropical waves come off of it at africa. And a ? for right now is is it on the move north.

It shifts north and south over the course of the year, generally between 0-12N. It fluctuates between moving north and south from day to day, often as disturbances ride along it. It generally "bottoms out" near this time of year, e.g. reaches its southernmost extent, and will begin to creep further north as the season approaches.

When Do tropical wave start sputtering out and coming in to the atlantic and crossing through Caribbean?
Does it have to do with a certain height the ITZC is at.

Tropical (or easterly) waves occur throughout the year, albeit with an increased frequency and amplitude toward hurricane season. It doesn't have so much to do with the location of the from a north-south standpoint as it does other supporting factors toward their development.

These links are to 5 Day Hovmoller diagrams for the Tropical Atlantic.
They are basically strips of satellite photos along the respective areas. A 5 day freeze frame.
As Clark said there isn't a lot of amplitude in the right now. Using these diagrams you can visualize the day-to-day movement of each area.
You could print a page of each one to see the movement.
