Sounds like you have too much fuel, drop the fuel to about 15-20% (30-40K lbs) turn FCGMS on and set to about 40% MAC.
That should allow a touch down at about 160kts with full flap, using spoilers if needed.
You can also mitigate against the nose dive by adding nose up trim on approach.
When full the B-1 is bloody heavy, it doesn't get off the ground until 180kt and is a slug up until 220-240. Landing with a high% load of fuel requires a higher landing speed.
Most heavies have a base approach landing speed based on a nominal fuel qty e.g. 160kt @ 30Klbs, and add a given no. of kts for every 1000lb over the base figure i.e +3kts/1000lb, so at 35Klbs you land at 175kt. They will usually have a max landing wt factoring airframe, fuel, and stores/cargo.
