New To jQuery and Mobile App Dev. Need Recommendations

I want to build a car parts interchange app.  Basically I want the app to allow the user to select three fields from drop down menues: year, model, and part, then perform the search against a database and then I want it to return "This part is interchangeable with:  (list all of the cars the part interchanges with).

What I need to know is:
1.  Is this possible to use drop down menus for search queries against a dataase?
2.  Is it possible to have it so that the app database is stored locally on the mobile device?
3.  Would SQLite be the database platform?
4.  Can this be built in jQuery?

I just need information to point me in the right direction so I can get started.
