[Q] ROM flash and data issue.

This is my device information now:
Rocket ROM XXLSZ
Kernel Version: 3.0.31 -906407
se.infra@SEI-46 #3
SMP PREEMPT date information

And I want to update to [KitKat][4.4][Omni]Team Asylum Omni 4.4 Naughties™ .
Does I belong to the follow:
"If coming from any other safe kernel except Philz older than v3.99 or Speedmod:

1. Copy Gapps and Asylum Omni Zips to your SDCard
2. Boot into Recovery
3. Wipe data and dalvik cache
3. Flash Asylum Omni zip
4. Flash Gapps zip
7. Reboob
8. Don't restore system stuff or apps + data using Titanium, it might cause issues"

If I can't restore apps +data, can I download the apps and just restore the data?

I can post question due to the policy, so I post here. Any reply may help a lot, thanks!
