From Numerical Models for Differential Problems by Quarteroni:

• 2.1-2.5
• 3.1-3.5
• 4.1-4.6.3
• 5.1
• 6.1-6.5
• 7.2.2-7.2.3
• 11.1-11.6
• 8 (just the idea, what you need is covered by the notes.)

Notes (at It's learning):

• Implementation of FEM in 1D
• Implementation of FEM in 2D
• Spectra of the continuous and discrete Laplace operator

All exercises and solutions.
