1) I have no idea how many characters, do what feels natural. Take a look at free-site descriptions already listed. From memory, your description was fine. Even if it is fine, expect some linklists to change or rewrite that description.
IMO, use correct punctuation in your description. I've yet to run into a script that breaks with a period in the description, yet I know of a few that edit the descriptions just to add the period.
2) Yes I have.
3) Depends. Small linklists up to 72 hours.
Some but not all large linklists can take from 4-8 months.
4) I suggest working with 2-3 categories you are comfortable with. No LL owner wants to see you submit to the same category with the same sponsor every day. Besides, diversified categories can help keep you out of a sales slump if one niche goes cold for some reason.
5) One LL I submit to limits the title to 3 words, so all my titles are 3 words, I don't count characters. If I didn't have that limit I would consistently use 4 words.
Your welcome.
