TPMS sensors; still VERY confused, 2005 Crossfire Limited Coupe – Please help!

Hello. I'm a newbie to the Crossfire forum and this is my first post/question (after reading lots of great posts). I have a 2005 Crossfire Limited Coupe that's about to get new TPMS sensors (...apparently the '05 Limited's/SRT-6's are a particular pain in the rear!). Let me begin by saying: (a.) by no means am I an auto mechanic, (b.) I’m auto dealership adverse, (c.) my sensors will be replaced along with new tires […tires perhaps Michelin, perhaps purchased from Costco..?], and (d.) I assume it’s best for me to purchase replacement TPMS sensors online [?].

So, here’s what “I think I understand that I need”:
1. Four Schrader TPMS sensors; either #20028 or #20066, since either are possible from my ’05 Limited (these replace OEM parts #5096808AA or #5142340AA respectively @ $65/ea. [@ sub ttl. $260]);
2. The original sensors must be checked before determining which of the above part numbers I need to purchase (i.e., that a VIN will not suffice for determining proper sensors for this year model);
3. I also will need four Schrader TPMS Service Kits #20013 that include the rubber seal for the rim, valve, nut and cap for each sensor (@ $6/ea., @ sub ttl. $24; therefore, @ parts ttl. $260 sensors + $24 parts kits = $284)
4. That ONLY a Chrysler dealer can properly install these TPMS parts such that the new sensors are “programmed properly” and the car is “trained properly” to recognize their ID’s (a.k.a., so that the damn car works properly).

Here are my questions:
A. Are Schrader sensors still the best option (as of 2.25.16)? What about the “self-programming” Denso sensors I see at CarID.com?
B. Assuming Schrader sensors are the best option, how does one “check” the original sensors to determine which replacement part number is needed? (I presume the tires have to be off, OEM part numbers are communicated to me, and then I order the Schrader parts. This seems like a very cumbersome, two-step tire removal/re-installation process [?].)
C. Given only a Chrysler dealership can perform this process: (a.) will they actually comply with [i.] all the steps presumably involved in #B, [ii.] install customer-purchased sensors and tires, (b.) does anyone have any idea of what a dealership might charge for this?
*D. Should the TPMS installation process and the new tires installation process be treated separately?
E. Can anyone recommend a preferred provider of these TPMS sensors (online or otherwise)?
F. Can anyone help me to simplify this process for best results at the best price?

Any advice is greatly appreciated! Thank you in advance!
