Do you think if I politely asked the management team that I could send away a CD cover or a mini autograph book and get the band to sign it? Because I was dead set on meeting them after a concert but had to leave before they came out

If you want an autograph but can't see them anymore on the tour, You still can send them a mail via post to:

Lordi c/o Sony Music Finland
Tallberginkatu 2 A 5
00180 Helsinki
Finland

When you want to send a mail to one member specifically, you can mark the envelope with the band member's name.
Maybe ad international reply coupons to your mail so they don't have to pay the postage.
Be sure to have a lot of patience since the band is very busy. I'm sure they will replay, but I can't tell you when.

The band had some very nice autographed photos on the tour also.

Never seen such ones here in Sweden and the mail office staff said they didnt have that. :/
But yes do as monsterboy said and have a very long patience

How long does the band take to exit the venue after gigs thanks.

Varies. Sometimes very quick, sometimes it can take hours. Just have patience and wait And most importantly, is to have respect. If any of the members look sick or ill or tired, it's better to leave them alone. Their well-being is more important than an autograph. : )
