I wouldn’t listen to the EWTN Masses for guidance on Latin pronunciation. Listen to a recording of a good choir or soloist (whose native language is not German- they pronounce Latin differently)- they do it right. Latin is pronounced very similarly to Italian- so an italian choir or soloist singing something in Latin would be good to follow.
I wouldn’t make a big deal about pronunciation, but if you are going to pray in another language, you should recognize and try to project the beauty of it. Most importantly, however, you should be able to think in that language- at least the prayers, otherwise they are little more than sounds (this is true for singing and reading literature as well- not just praying). Don’t go through each word, translating it as you go- pass the translation barrier- simply think the words in that language, and understand what they mean.
Here’s a pronunciation guide to help you pronounce anything in Latin. The words to the Our Father will not be hard to learn using this.
Vowels
a- ah
e- eh
i- ee
o- oh (more like the o in orange, if it is followed by consonant though)
u- oo (a minnesota oo- NOT one with a southern drawl to it)
uu- oo followed by oo (as in good)
ae- a long A sound (one sound throughout- not eh+ee)
oe- eh
Consonants
B, D, F, K, L, M, N, P, Qu, S, T, V- as in English
C ch if followed by E or I, K if followed by A, O, U, or a consonant
CC- breaks the previous rule- pronounced CH
CCH- pronounced K
TI followed by a Vowel- pronounced TSEE (Orationem)
G- hard if followed by A, O, U or a consonant, soft otherwise
H- silent if at the beginning and end of a word
J- pronounced Y (sometimes J’s are replaced with I= Iesus)
R is rolled like it is in Italian, or flipped like it is in British English.
X is pronounced Z if at the beginning of a word- X otherwise
No W, Y, or Z used in Latin.
