All cleric types can be dualled to monk. All monks can be dualled to all cleric. However if you dual from monk to cleric you lose the ability to gain more monk levels, unless you chose the correct monk type, which can be dualled to painbarer of ilmater and still later be able to gain more monk levels.

krunchy, my first cleric ever was a tempus half-orc. Personally I found him great, but that's because I like summons.

That said, although the extra spells are great, they are only two per level , and not something that will make or break a cleric. I usually look at it more roleplay-wise when choosing a cleric domain, with special abilities having second priorities, and spells coming last.
