Question about tagging Mp3 and also hotcues

Hi just a quick question,
Okay i have A lot of old skool viynl i have saved to dvd's over many years before i sold my viynl, I have now put some of it to my storage hard drive, I have started to convert to mp3 so i can add various tags, but i am raring to get doing some mixing and i could be tagging for weeks, so my question is;
1) If i analyze these tracks in Cross ready to mix, but then go on to add these fields, from filename to artist and tital also the year,Group & Comment at later date, will i need to re-analyze these again or will the Cross beat gridding still be okay.
2) If i save hotcues, but then decide to move and play with my hot cues on the fly for creative purposes, will these new hotcues be stored again, or will they revert back to when i first set them, personally i am guessing they will store as in the last state used, if so a funtion request, would be to have them locked and still be able to change them on the fly, but on my next session they revert back, or is this alreday possible ?
Thanks
