So again, what does this note really mean?

What they are trying to do (IMHO), is to keep you from performing a procedure turn at the feeder fixes. If you are coming from the west, use FAK. From the east, use HPW. Notice, they are limiting you to a 120 degree cone of entry.

well, then which one do i use if i am coming from the position i mentioned? i can't use either....

Why not go direct to JEDEL?

i want to know if ATC gives me direct to one of those VOR's to start the approach, do i have to say no?
If going direct to those VORs from your position puts you on one of the prohibited radials, then I'd say yes... you'd have to say no.

250 or point 65;

You are reading way too much into this. If you intend on filing and flying the feeder routes, then you must be within the radials listed. The notes are restricting the use of the feeder fixes if your turn exceeds 120 degrees. We don't know why they are doing this. It could be for ease of traffic flow, obstacles, comm out complications, or airway confliction.

From the references below, it appears turns greater than 120 degrees at IAFs (I know, not feeders) require course reversals. I am assume they have applied the same restrictions to the feeders in this case. They want you to fly from the feeder to the IAF without any major turns (course reversals).

If you plan to enter the TAA from a radial that isn't compatible with the notes, then according to the notes, you can't fly this approach (Procedure NA).

Get your FAR / AIM:

Reference page PFG F-1 (Pilot controller glossary)

FEEDER ROUTE- A route depicted on instrument approach procedure charts to designate routes for aircraft to proceed from the en route structure to the initial approach fix (IAF).

Reference page 5-4-7 "Terminal Arrival Area"

The TAA provides the pilot and air traffic controller with a very efficient method for routing traffic into the terminal environment with little required air traffic control interface, and with minimum altitudes depicted that provide standard obstacle clearance compatible with the instrument procedure associated with it. The TAA will not be found on all RNAV procedures, particularly in areas of heavy concentration of air traffic. When the TAA is published, it replaces the MSA for that approach procedure.

Reference page 5-4-14

7. Just as the underlying “T” approach procedure may be modified in shape, the TAA may contain modifications to the defined area shapes and sizes.Some areas may even be eliminated, with other areas expanded as needed. FIG 5-4-10 is an example of a design limitation where a course reversal is necessary when approaching the IF (IAF) from certain directions due to the amount of turn required at the IF (IAF). Design criteria require a course reversal whenever this turn exceeds 120 degrees. In this generalized example, pilots approaching on a bearing TO the IF (IAF) from 300 clockwise through 060 are expected to execute a course reversal. The term “NoPT” will be annotated on the boundary of the TAA icon for the other portion of the TAA.

Reference page 5-4-6 Approach Clearance (lots of good stuff here)

I hope this helps.

In my humble opinion, all 90 hours anyway... If atc had cleared me direct to one of the VOR's and my course to that VOR was outside of the 'cone of entry' I would hope to hear, 'expect vectors for the approach.' And if ATC had cleared me for the approach while on an inbound radial to the VOR outside of the 'cone of entry,' I would query atc and advise them of the discrepency, and expect to get vectors from them. So to answer the question, yes.
