The grammar dictionary I recommended to you has kanji, romaji, and an English translation for each example sentence (the later two additions cut the romaji). Since all the sentences are based around the grammar point, they should be very easy to understand after reading the explanation. Making them into flashcards with key points as the answer side is a great way to drill more complicated expressions.
You can look up words you don't know fairly easily with a dictionary, but it's rarely the case with functional words, which can take some background understanding. Outside of sources with translations/explanations, you should probably stick to within the limits of your own understanding; pick out new vocabulary and kanji you can't read contained in sentences you can roughly understand. As you progress, the restrictions will become less and less.
Another way to avoid getting caught out is to learn idioms. You could lookup あご andつかう, and still have no idea what あごでつかう means. These sort of expressions also tend to be used frequently in daily conversation, so they're very useful to learn. Kodansha's Dictionary of Basic Japanese Idioms has about 900-1000 of them, including yojijukugo, with explanations and a number of example sentences with translations, which are generally very easy to understand, so they're ideal for flashcards. Could be worth checking out.
