Drive Cycle monitors Issues

Any help or advice would be awesome:
Just went over 100k on my 04 Disco and I needed to replace many components:
1. Cat System
2. O2 sensors (DS and US)
3. New plugs and wires
4. New Injectors
5. Gaskets
6. New PS pump and tubes
Everything checked out, no leaks, no dash lights, no dtc's (stored nor pending), etc.

I ran through the drive cycle and then hooked up my OBD2 (AB's TekPro 3000LR) to check out all monitors and this is what it's showing:
- Evap system = WAIT
- Heated Catalyst = NS
- A/C Refrig - NS
I've ran through the drive cycle 2 more times plus changed out the MAF, still no luck.:banghead: I've driven over 300miles to try to ready the monitors. Not sure what to do??? I'm in PA therefore if I fail emissions 2x I'm eligible for an emissions waiver if you've spent $150 and over in parts/labor and diagnostics (no shop will EVER tell you that). http://www.drivecleanpa.state.pa.us/...q_customer.pdf

But I'd still like to get to the bottom of this problem..
Any ideas??
Thanks

NS likely means not supported, so you're fine there

Do you have to have all of them complete to pass? Here 2001+ is allowed 1 not ready non-continuous monitor, 2 allowed for older vehicles.

Robertf:
I wasn't sure if NS meant/means "not set" or "not supported," i haven't taken it in for emissions/inspection yet therefore they will be able to tell me then. And YES, you're right about the one monitor being not-ready for 2001+ vehicles.
Thanks
