The more important consideration is what domains you take. Domains for Clerics are a bit like specialization schools for Wizards; they establish what type of Cleric you're going to play. You stated a preference for being proficient in combat, and there are usually a couple of ways to go -- but you have limited sources, so the best bet is taking the War domain. The problem there is that Pelor doesn't have War in his portfolio. You might want to consider going with Wastri (LN) instead, to get that deity's favored weapon: a glaive. (Wastri also has Animal, Law, Purification, and Scalykind.) Add in armor spikes and you'll threaten both close and with reach, which makes you much better in combat.

Almost any non-Evil deity will work as far as being a healbot, so there's not much restriction in that regard.
