As a rogue, the majority of your damage comes from sneak attack. If you have no teammates, then all enemies will focus on you, and this no sneak attack. Bluff can help, but its slow and doesn't do much against enemy groups.
Ranged attacks also have some of teh slowest attacks rates of any weapon style, meaning that you will be getting pitiable DPS even in a group. Most rogues like to go with Two Weapon Fighting in order to maxmize their sneak attack output (More attacks, more sneak attack!)
None of the rogue PrEs mesh with bow-based ranged combat. Theif-Acrobat is all about staves, mechanic likes its repeaters, and assassin is built for melee. granted, all three offer some universal bonuses, but far less than using the suggested weapon-types of those PrEs.
Edit: This build lacks self-sufficiency as well. You will have to rely on potions for everything in your first few levels, and then wait for your UMD to catch up before you can use the "good" self sufficient items, such as cure serious wands and heal scrolls. You will also have to wand/potion your resists/protections, which will make them far weaker than if you had cast them yourself (Barring finding higher level wands/scrolls/potion, which are rare to drop).
Overall, i would highly suggest staying away from a mostly-rogue build for a solo character (Especially if you're new to the game).
Edit:
As a prerequisite for Arcane Archer, i assume.
