I'm mostly interested in soloing content. When I get the urge for group stuff, healing is what I like to do. My concern is that leveling a summoner (a good solo class from what I've read) will make it harder to get into groups because it is a DPS, and leveling a healer will mean not being able to solo stuff.

I love healing and I love soloing. Where should I start in terms of leveling? Also, which healer is more slap-noob friendly? Sorry if this sounds scattered.
