In formal contexts, I would go with "e.g." and "i.e.", with two periods and without a whitespace. The spellings without periods are quite popular, but informal. For example, Merriam-Webster does not have an entry for either "eg" or "ie". Wiktionary marks "eg." and "eg" as informal, and offers the following usage notes:
It also offers the following usage notes for "i.e.":
Personally, I would argue that there's no need whatsoever to italicize "e.g." or "i.e.". Both expressions are extremely common in English, and have been for a long time. They are full-fledged citizens of the English language, and as such, they do not have to be italicized as if they were foreign words.
Most style guides I have seen also say no italics for e.g. or i.e. — they are common Latin abbreviations.
