2, is Athens weight restricted and thus Paz capped?

Yes, you have to pay the taxes. All you do is get a non-rev ticket for yourself on wings.
There used to be a time back in the 90s where it was possible to list yourself on the GenDec as a way to circumvent paying that tax. But someone had a problem with that and thus this system of putting yourself on the General Declaration went away. Remember though that this tax is not revenue that goes to the airline (supposedly). This tax is only the international/US - departure/arrival -airport fees/destination taxes amount. (And yes, the UK is one of the most expensive TAX place, when it comes to travel.) Even if you buy a regular fare ticket, that same tax is still slapped on it. So, by buying yourself the ticket and showing the receipt at the gate, you are covered.
As for the just showing up, please remember this. Many US Airlines use an array of separate handling companies from the security all the way to operations. Usually there are some direct employees but the majority of the people that you will encounter are outsourced.
Some of the supervising agents have no clue of how stuff works in the USA, especially with regards to jump-seating. If you go in Uniform and manage to get through the security check-point all the way to the gate, you may find yourself in front of an angry gate supervisor for not checking in. I don't recommend doing that as you may have to really put your ego aside in order to take the abuse that comes with getting on the aircraft. (Been there done that - took the abuse - and got on the plane.)
Check in at the counter, and let them know that you will want to have the option as a jump-seater. Make sure you stay on the stand-by list as they will also attempt to tell you that you can either jump-seat or non-rev, but not do both. You see, depending on where you are, you may find yourself in front of someone who is a bit out of date on the policy, and if you try to clarify, they will tell you that America doesn't know what they are doing. (...yep happened to me one time too...)
So to recap...
1) Buy your round-trip Non-rev ticket on your airline (wings, jetnet, deltanet or whatever your respective airline is) (You have to obviously list yourself on any flight of your intended pairing to get your ticket.) You should not be able to use a ticket paring of BCN-PHX when standing at the counter in LHR, as Spain has one of the cheapest entry/exit fees, but mistakes can happen and I have seen them happening even in the traveling party's favor. Still, don't try to use a ticket from one country when at the airport of another one.
2) Re-list yourself for your flight if you change dates. (In the US, at least in the case of AWE, I believe that there is a special number you have to call to get listed for international flights)
3) check - in at the counter (when at the out-station) and specify that you want to non-rev and also list yourself for the JS. They may involve two different lengthy processes.
4) Go to the gate and make sure that the gate supervisor does not leave you behind. Try to intercept the operating crew to let them know that you are there. They may in the end be help to you getting on if the gate agent is acting strangely.
IF YOU SKIP STEP 3 and just show up at the counter make sure you have your receipt, and try to get the gate supervisor to use your PNR to list you on the flight..... (THIS IS WHERE YOU MAY OR MAY NOT GET ON DEPENDING ON HOW PISSED THE SUP IS FOR YOU SHOWING UP AT THE GATE UNANNOUNCED)
THIS IS ALSO WHERE DOCUMENTATION RELATED TO THE NO-JUMPSEAT DENIAL LETTER MAY COME IN HANDY...
---------THE BOTTOM LINE IS THAT JUMPSEATING OUT OF EUROPE MAY BE A LITTLE BIT OF AN EXCITING ADVENTURE-----
Regardless of whether you try to use it as a last resort to secure your return to the US after going the normal nonrev route or whether you show up unannounced, it may result in an interesting story to tell someone down the line.
Good luck
WEIGHT RESTRICTIONS CAN ALWAYS HAPPEN...
