Your guesses are correct :)

Rules for spelling without niqqud Every letter that appears in vowelled text also appears in unvowelled text. After a letter vowelled with a kubuts (the vowel /u/), the letter ו appears: קופסה‎, הופל‎, כולם. After a letter vowelled with a holam haser (the vowel /o/) the letter ו appears: בוקר‎, ישמור. After a letter vowelled with a hirik haser (the vowel /i/) the letter י appears: דיבור‎, יישוב‎, תעשייה. The letter י does not appear in the following situations: Before a shva nah, for example: הרגיש‎, מנהג‎, דמיון (but "קילשון", because the lamed has a dagesh, and so the shva under it is a shva na); Words whose base forms do not contain the vowel /i/: לבי ‎(לב)‎, אתך ‎(את)‎, עתים ‎(עת); After affix letters, like in מביתו, מיד, הילד, and also in the words: עם‎, הנה ‎(=הִנֵּה, and inflected: עמי etc., הנו etc.), אם‎, מן; Before יו (/ju/ or /jo/): דיון‎, קיום‎, בריות‎, נטיות. After a letter vowelled with a tsere (the vowel /e/) the letter י generally does not appear )ממד ‎(=מֵמַד‎), אזור ‎(=אֵזוֹר‎)), but there are situations when י does appears (תיבה‎, הישג) and in words in which tsere replaces hirik because the presence of a guttural letter (אהחע"ר‎): תיאבון ‎(שיגעון‎), תיאבד ‎(תימצא). Consonantal ו (the consonant /v/) is doubled in the middle of a word: תקווה‎, זווית. The letter is not doubled at the beginning or the end of a word: ורוד‎, ותיק‎, צו. Initial ו is doubled when an affix letter is added except for the affix ו- (meaning "and-"). Thus from the word "ורוד" is derived "הוורוד" but "וורוד" (that is, וּוֶרד). Consonantal י (the consonant /j/) is doubled in the middle of a word, for example: בניין‎, הייתה. The letter is not doubled at the beginning of a word or after affix letters: ילד‎, יצא ‎(=יֵצֵא‎), הילד. Still, consonantal י is not doubled in the middle of a word when it is before or after mater lectionis: פרויקט‎, מסוים‎, ראיה ‎(=ראָיָה‎), הפניה‎, בעיה.
