It seems that your opponent don't have very mobile army (only one Rhino) so there isn't going to be any "Rhino rush" coming at you and that's a good thing
Here's some advises:
1)
Get as many Plasma rifles you can on your suits and Pulse rifles are also good so solid line of Fire Warriors are never a bad thing
2)
And couple of Broadsides are good against his Predator and Dreadnought.
3)
If your opponent has that new Codex you should know that he can now choose which Champion is possessed by the Greater Deamon (he don't have to tell you who) and the host can resist the deamon so it has good change that the Bloodthrister is on your lines even when you have the change to kill it!
And if the host is killed the damn thing is possessed automaticaly
4)
I advise not to get any Kroot as all of your opponets assault units have many attacks so I doubt Kroot have any chance of surviving the first round of combat as their saving throw is either 6 or -.
