Well done for emailing your pm, I'm sure if he/she thought your lateness was a problem you'd know already, so please try not to worry. Actually, I've got to go for a meeting soon about my lateness, but then again, I've been a very naughty girl... Oops
In regards to your IFA's, just ask the purser on your next few flights. Especially new pursers have to do them to get past their development programme. If you're doing a lot of shorthaul at the moment I'd recommend that you go no4 (if you're lucky enough to have 4). If there's only 3 crew, and light loads in Club, the purser could send the other crew member to work in Club and then come and work with you on a sector. That's how I get round it anyway. And it works especially well on domestics... Good luck, I'll do an IFA on you if you'd like, no problem.
