Welcome to the site! As this is for you a practical question, please CYLOR rather than relying in practice on answers here. – msh210 Aug 5 '11 at 5:59
Thanks! Will do. Sort of lost in the proper decorum of a SE site. But in any case, how about the first two questions? – Shmuel Aug 5 '11 at 6:01
I've edited the question so that it doesn't look like a request for personal halachic advice. It seems clear that there are two questions here and that it might make sense to split them into two separate posts. – Isaac Moses Aug 5 '11 at 6:27
