Dating Dilemmas

was just wondering what yeshiva/ BY type people feel about the following :

1) going places like bowling or shooting pool on dates

2) complimenting guy/girl on clothing (i.e. nice tie , or nice necklace) if Ok what date is it acceptable?

3) guy walking girl out of car when returning from date

4) sharing a portion of food when eating out

5) Is it ever allowed to be asked to be taken home ?
