hi, i am also new here in Doha :)

well, as far as I know, 1 lang ang Catholic Church dito sa Doha. medyo malayo sa 'downtown'.

courts? no idea yet, haven't really gone out. mainit! hehe

if you are from KSA then I guess you would really find Doha a bit similar to KSA (sabi nila).

as for the working environ, well, since nasa industrial area ka so you should not expect na magiging 'lively' siguro ang surroundings hehe.

anyways, goodluck & welcome to Doha :)
