Welcome!!!
Both of these past tenses are very important to learn and master.
The imperfect tense has only three irregular verbs (ir, ser, and ver). Other than those, the verbs are easy to conjugate. There are websites, including this one, that list the conjugation endings. You need to memorize one set of endings for the -AR verbs, and another set of endings for the -ER/-IR verbs.
You also need to memorize two different sets of endings for the preterite tense - one for the -AR verbs, and one for the -ER/-IR verbs - but the preterite tense has many irregular verbs. You'll need to commit those to memory (generally, only the stem needs to be memorized - the normal preterite verb endings apply). The most common verbs are usually the irregular verbs in the preterite.
If you want to supplement your learning with a visit to a couple of websites, I could recommend a few. But I would just learn the endings and practice, practice, practice.
