Starwood has timeshares in both Palm Springs and Arizona, and SDO is considered to be the most cost effective II trader - so it would be a good trader for you - but you need to buy a Gold Plus week to have good trading power.
However, you stated that you were looking for a home resort, and I would not consider Scottsdale to be within driving distance from Fresno.
A good option for you would be to buy a Tahoe timeshare as your home resort (every other year deed) and an SDO timeshare for a trader (every other year deed.)
Here are all the Starwood timeshares -

You would be able to trade into all of the Starwood timeshares (except for Harborside and Westin St. John) by trading SDO through Interval International, as long as you are flexible.
Note however that trading for the prime school holiday weeks is far more difficult (Christmas, New Years, Easter, etc.) If you are flexible about when you travel - you will have a lot more options.
Be aware that exchanging is not like making a reservation - it requires some knowledge, skill, and persistence to be successful. It's also not free - there are yearly II membership fees of about $100 and exchange fees of $120-$150 per exchange - on top of your maintenance fee.
On the deed they sent me it said we were getting 1/52 is that normal?
That refers to the fact that you own one week out of 52 weeks in the year.
