''grave e importante''
''e'' means ''and''.When do you use ''e'' and when''y''? Are there any rules?

Yes: you use "e" when the next word begins with an /i/ sound, as in "importante" or "historia".
Notice that in words like "hielo" there is no such sound (the first sound is /'jelo/) in standard Spanish (even though some people actually say /i'elo/), so it must be "Agua y hielo" (never "e hielo"), since there theoretically there is no /i/ sound. The /j/ sound in the diphthong "ie" of "hielo" is standard Spanish, not a regional oddity.
Use e (meaning and) prior to a word that begins in either i or hi.
Not really. You can't say "e hierro" or "e hielo", since the ascending diphthong "ie" theoretically starts with a semi-consonant /j/. You use "y" in these cases.
This rule and the one that directs you to change the o to a u, as in de una u otra manera,. have the effect of making the phrase easier to pronounce by sepertating the sounds. The rule is the same: use a u when the next word begins with an o sound. Likewise, use an e when the next word begins with a i or y sound, asi in Padre e hijo.
Oh yes there are, there are several posts on this subject, let me see if I can post a link to them.
This is a link to my own post ,there are others as well
Yeah it's pretty simple. Switch "y" to "e" when it comes before another word that also has a "y" sound. This helps differentiate the two words.
