Hey Rob,
the best thing you should do is to have a look into the hashcat wiki http://hashcat.net/wiki/ and for your particular problem, see here: http://hashcat.net/wiki/doku.php?id=mask_attack
Your points:
1. Use your defined mask together w/ pw-min, pw-max if you want to restrict the password length, if you want to reduce the keyspace instead i.e. the chars used see answer 2.
2. you can define custom charsets if the default charsets (Built-in charsets, ?l ?u ?d ?s ?h ... ?a) do not fit for you, use -1 (a number *not* ELL), -2 up to -3 parameter: e.g. -1 abcd and your mask could contain now this charsets as password?1 where ?1 is either a, b, c or d
3. same as in 2. applies here, but you put numbers in ?1
4. either you are able to put this resriction directly into the mask (*not* very likely) or please try maskprocessor (http://hashcat.net/wiki/doku.php?id=maskprocessor ) and also see this topic http://hashcat.net/forum/thread-2161.html
5. see ?s
Hopefully this helps you to get started ;-)
