The best way to connect to Angels and spirit guides and even spirit is by going within. I suggest meditation techiques or asking your angels to come through before you go off to sleep.
Check out the angel message board and pys development message board. Also check out the meditation message board to see if there is a mediation for connecting to your spirit guided. You can use this similar method to connect with angels.
Dont expect anything straight away, this can take time and soem are happy enough just knowing or feeling there presence near by :)
There is heaps of info on the net on Angels, just bring up google and do a search :)
